Surprised that the UK didn't get any M51 Skysweepers or equivalent like the 3"/70 naval gun. Doesn't have the sheer rate of fire of the Bofors 40mm/L70, but the bigger shells allow proximity fuses.
The 42mm guns were aimed at that role, no proximity fuses IIRC but significantly higher rate of fire and shorter time of flight than the Bofors.

This is BAOR's artillery order of battle in April 1961 according to Pages 51 to 56 of "The British Army in Germany (BAOR and after): An Organizational History" by Graham E. Watson and Richard A. Rinaldi.

1st Army Group Royal Artillery (Field).
27th Guided Weapons Regiment (Field) RA (6 &137 Batteries) with Corporal SSMs.​
47th Guided Weapons Regiment (Field) RA (3 & 4 Batteries) with Corporal SSMs.​
24th Missile Regiment RA (51 & 76 Missile and 2 & 34 Heavy Batteries).​
The missile batteries had Honest John SSMs.​
The heavy batteries had M115 towed 8” howitzers.​
39th Missile Regiment RA (19 & 36 Missile and 75 & 171 Heavy Batteries).​
The missile batteries had Honest John SSMs.​
The heavy batteries had M115 towed 8” howitzers.​
50th Missile Regiment RA (15 & 21 Missile and 33 & 78 Heavy Batteries).​
The missile batteries had Honest John SSMs.​
The heavy batteries had M115 towed 8” howitzers.​
12th LAA Regiment RA (T, 9 & 34 Batteries) with Bofors 40mm LAA guns.​
94th Locating Regiment RA (14, 73, 152 & 156 Batteries).​
1st Division (7th & 20th Armd Bde Gps).
7th Armoured Brigade Group.
4th Field Regiment RHA (F, G & I Batteries) with M44 self-propelled 155mm howitzers.​
20th Armoured Brigade Group (from 4th Div to 1st Div March 1961).
1st Field Regiment RA (A, B & E Batteries) with M44 self-propelled 155mm howitzers.​
2nd Division (6th, 11th & 12th Inf Bde Gps).
6th Infantry Brigade Group.
40th Field Regiment RA (38, 78 & 137 Batteries) with towed 25pd gun/howitzers.​
11th Infantry Brigade Group.
19th Field Regiment RA (25, 28 & 67 Batteries) with towed 25pd gun/howitzers.​
12th Infantry Brigade Group.
6th Field Regiment RA (H, V & 132 Batteries) with towed 25pd gun/howitzers.​
4th Division (4th Gds & 5th Inf Bde Gps).
4th Guards Brigade Group.
49th Field Regiment RA (55, 127 & 143 Batteries) with towed 25pd gun/howitzers.​
5th Infantry Brigade Group.
45th Field Regiment RA (70, 116 & 176 Batteries) with towed 25pd gun/howitzers.​

That's a total of 44 batteries distributed amongst 14 Regimental Headquarters (RHQs).
  • 10 batteries of SSMs distributed amongst 5 RHQ.
    • 4 batteries of Corporal SSMs distributed amongst 2 RHQ.
    • 6 batteries of Honest John SSMs distributed amongst 3 RHQ. (which also had the 8in howitzer batteries).
  • 3 LAA batteries with Bofors 40mm guns distributed amongst 1 RHQ.
  • 27 batteries of tube heavy, medium and field artillery distributed amongst 7 RHQs.
    • 6 batteries of M115 towed 8” howitzers which distributed amongst the Honest John SSM regiments.
    • 6 batteries of M44 self-propelled 155mm howitzers distributed amongst 2 RHQs.
    • 15 batteries of towed 25pdr gun/howitzers distributed amongst 5 RHQs.
  • 4 Locating batteries distributed amongst a single RHQ.
The net increase since April 1958 was 8 batteries distributed amongst 2 RHQs.
  • The reductions (which totalled 11 batteries and 3 RHQs) were:
    • 7 medium batteries and 2 RHQs.
    • 3 LAA batteries and 1 RHQ.
    • 1 AA control battery.
  • The additions (which totalled 19 batteries and 5 RHQs) were:
    • 4 batteries and 2 RHQs of Corporal SSMs.
    • 6 batteries and 3 RHQs of Honest John SSMs.
    • 6 batteries of M115 towed 8” howitzers, which were distributed amongst the 3 Honest John regiments.
    • 3 locating batteries, which were added to the existing locating regiment.
Therefore:
  • The AA capability of BAOR had been reduced by half to 3 batteries & 1 RHQ of Bofors 40mm guns.
  • There had been no change to BAOR's field artillery, because there were still:
    • 6 batteries & 2 RHQs of M44 self-propelled 155mm howitzers - 3 batteries & 1 RHQ per armoured brigade.
      • And.
    • 15 batteries & 5 RHQs of towed 25pdr gun/howitzers - 3 batteries & 1 RHQ per infantry brigade.
  • The departure of the 7 batteries & 2 RHQ with 5.5in howitzers was offset by the arrival of the 6 batteries of towed 8in howitzers.
  • The SSM capability of BAOR had been increased from nothing in April 1958 to 10 batteries (4 Corporal & 6 Honest John).

Part of Post 88.

This is a summary of the entry on the M109A2 in Terry Gander's "Encyclopaedia of the Modern British Army - 3rd Edition" which was published in October 1986.
  • The first paragraph says that the M109 entered service with the British Army in 1965 and that in 1978 these vehicles were fitted with longer barrels known as the M185 to give their self-propelled carriages a new designation of M109A1, later M109A2.
  • The next paragraph says that the M109A2 is the standard equipment of the Royal Artillery's medium self propelled batteries based in Germany. The first two vehicles were obtained for trials in 1975 and that the barrel retrofit programme was scheduled to be completed by the end of 1978.
  • The third paragraph is a description of the vehicle.
  • The fourth paragraph says that the M109A1s now in service have been updated to a new standard known as M109A2, that new vehicles have been purchased from the United States with all up-to-date modifications incorporated and finally that these "new" vehicles are sometimes referred to M109A3s.
  • The fifth (and final) paragraph says that there is little sign that the SP70 will enter service as scheduled and that in the meantime numerous changes can be made to the basic M109A2 to improve its range and all round performance. Several concerns are now promoting new and longer barrels for the M109A2 and revised turrets to go with them. Autoloaders are another option and some of these may be incorporated into future British Army M109A2s.
Therefore, based on that it looks like 40 vehicles were purchased in the 1960s, 2 were purchased in 1975 and 69 were purchased in the 1980s = 111. However, the designations are the opposite to what @OldBill17 wrote, i.e. the M109A1 vehicles purchased in the 1960s were updated to M109A2 standard and that the vehicles purchased in the 1980s were M109A3, while @OldBill17 says that the original vehicles were updated from M109A1 to M109A3 and the new vehicles were M109A2s.
Though Terry Gander was "on the money" with alot of his information, other information in his books is mistaken. I have a plethora of documents (literally thousands of pages worth) from Kew and FOI requests. My numbers are exact. I am currently updating my document. The 111 will read 119 in the new version as I have the 1989/90 stock planning guidance and it shows 96 UE (unit entitlement), 5 WMR, 14 ITO, UR, RP, PDS, & 4 R&D.
 
When I first read that statement I was completely nonplussed by it and at the time of writing this reply I am somewhat nonplussed by it.

The M107s and M110s weren't in the four divisions, they were part of 1st Artillery Brigade. Therefore, they weren't in the "Real World" and this "Version of History" divisional artillery orders of battle shown in Post 99.

For BAOR's full "tube artillery" order of battle in the "Real World" please see the list in Post 97 which you "liked" at 21:17 on Thursday 5th October 2023.

This is BAOR's full "tube artillery" order of battle in this "Version of History". That is the "tube artillery" of its four divisions (already listed in Post 99) plus the "tube artillery" of 1st Artillery Brigade.

1st Artillery Brigade - 12 M110, 24 M107 and 48 M109 as follows:
General Support Group North​
12 M107 - 32 Heavy Regiment, RA​
24 M109 - 27 Field Regiment, RA (but also part of 2nd Infantry Division - see below)​
General Support Group South​
12 M107 - 5 Heavy Regiment, RA​
24 M109 - 45 Field Regiment, RA (but also part of 4th Armoured Division - see below)​
Corps Support Group​
12 M110 - 39 Heavy Regiment, RA​
1st Armoured Division - 72 M109 as follows:
24 M109 - 1 Field Regiment, RHA​
24 M109 - 4 Field Regiment, RA​
24 M109 - 40 Field Regiment, RA​
2nd Infantry Division - 72 M109 as follows:
24 M109 - 27 Field Regiment, RA (but also part of 1st Artillery Brigade - see above)​
24 M109 - 100 Field Regiment (V), RA​
24 M109 - 101 Field Regiment (V), RA​
3rd Armoured Division - 72 M109 as follows:
24 M109 - 2 Field Regiment, RA​
24 M109 - 3 Field Regiment, RHA​
24 M109 - 49 Field Regiment, RA​
4th Armoured Division - 72 M109 as follows:
24 M109 - 19 Field Regiment, RA​
24 M109 - 26 Field Regiment, RA​
24 M109 - 45 Field Regiment, RA (but also part of 1st Artillery Brigade - see above)​

Totals: 24 M107, 288 M109 and 12 M110 - Grand Total: 324 tube artillery pieces.
1 BR Corps intended to fight with NO artillery in reserve, that is 1 & 4 Armd Div would have their three 155mm SP regts PLUS one Regt each from 3 Armd Div. The third Regt in 3 Armd Div was intended to support 33 Armd Bde which had a task of covering the Belgian sector until their deployment. The GSGs would each have one MLRS Regt and one FH70 Regt. Corps Reserve would be one MLRS Regt, however there was correspondence before Wall Fall about converting 50 Missile Regt into a fourth MLRS Regt if FOTL (follow on to Lance) was shelved by the U.S. The two TA Regts with LTG were intended to support any attacks against Soviet Airmobile/SPETNAZ/Para landings in the Corps rear. They also were intended to cover the Weser Bridges (all of which would have been wired for demo) and in a pinch they did have HESH rounds for the AT role (which if it got to that things would have been really bad)

So after the Abbot & M109 regiments had converted to AS90 and if 50 Missile Regiment had converted to the MLRS it would have looked like this:

Regimental titles are those in BAOR in July 1989.

1st Artillery Brigade - 72 MLRS and 36 FH70 as follows:
General Support Group North​
18 MLRS - 32 Heavy Regiment, RA​
18 FH70 - 27 Field Regiment, RA​
General Support Group South​
18 MLRS - 5 Heavy Regiment, RA​
18 FH70 - 45 Field Regiment, RA​
Corps Support Group​
18 MLRS - 39 Heavy Regiment, RA​
18 MLRS - 50 Heavy Regiment, RA​
1st Armoured Division - 96 AS90 as follows:
24 AS90 - 1 Field Regiment, RHA​
24 AS90 - 2 Field Regiment, RA​
24 AS90 - 4 Field Regiment, RA​
24 AS90 - 40 Field Regiment, RA​
2nd Infantry Division - 48 L118 Light Guns as follows:
24 L118 - 100 Field Regiment (V), RA​
24 L118 - 101 Field Regiment (V), RA​
3rd Armoured Division - 24 AS90 as follows:
24 AS90 - 26 Field Regiment, RA​
4th Armoured Division - 72 AS90 as follows:
24 AS90 - 3 Field Regiment, RHA​
24 AS90 - 19 Field Regiment, RA​
24 AS90 - 49 Field Regiment, RA​

Totals: 192 AS.90, 36 FH70, 48 L118 Light Guns and 72 MLRS Grand Total: 348 artillery pieces.

Except I'm an AS90 regiment short for the 4th Armoured Division because in July 1989 it had 2 Abbot and one FH70 regiment with the latter to be part of General Support Group South.

Yes, but if 33 AB didn’t have to cover the Belgians it would have went to 4 DAG (Division Artillery Group).
The lack of artillery was mentioned in many documents I have. There was a TA ORBAT Review in the 80’s. It was suggested that the TA form one or two FH70 Regts, presumably from guns transfered from the regulars. They would be replaced by M109s released upon entry of AS90 in service. Again Wall Fall overtook all this.
 
As I also mentioned, in a perfect world 1 BR Corps wanted an additional Inf Bde and Armd Bde.
The Armd Bde to fill out 4 AD releasing 19 IB to return to its role of defending the “Water Sandwich” (the land sandwiched between the canals south of Hannover and west of Hildesheim). The additional Inf Bde would replace 24 Airmobile Bde (which was going to the MN Airmobile Div) in the Corps Rear area.
 
As always, money was short, so the two Bdes that BAOR/1 BR Corps needed never materialized. But take note of the Parachute Regiment Group. PRG used the RHQ of the Parachute Regt to form an ad hoc Bde (it was called PRG to prevent the bean counters from getting excited) to control the three TA Para Bns holding Hildesheim. Hildesheim was key in the Corps plan as it was intended to pull back 7 AB after it covered 1 ADs deployment. 7 AB would refurbish in the Water Sandwich and then be prepared for counterstroke operations using Hildesheim as a pivot.
22 AB had four Battle Groups to make up for the loss of 19 IB defending the Water Sandwich. Elements of 6 AB (3 AD) would be detached to form defensive positions West Bank of the HILDESHEIMZWEIGKANAL until relieved by, possibly, the Dover based SAXON equipped Bn which initially had a TTW role of LOC duties from the Channel Ports to the Corps Rear. There was also plans to use use the SAXON equipped Bn in 24 Airmobile in that role also. 12 AB would hold the Div boundary in the South with 4 AD. 4 RGJ and 5 Queens (from 11 AB/ 4 AD) with extra MILAN Pls would most likely hold the Sibesse Gap. 1/51 HV (4 AD) had a role, also with extra MILN Pls holding the Finger Valleys leading to Alfeld. This of course could change and the TA ORBAT Review wanted to pull the TA Bns back for MHD and replace them with regular Bns in garrison in the UK.
Besides the extra Bdes 1 BR Corps also wanted the 13 AI/Mech (T) Bns to add a fourth rifle Coy & dedicated Aslt Pioneer Pl. Again this was more or less a wish list. DRAC thought he could have all BAOR Armd Regts strengthened to Type 57 (four Sqns) by the 1990’s, at least that was the aspiration.
When WARRIOR was fully deployed it was envisioned that each Div of Inf would always have two Bns in the AI role (the Queen’s Div with three Large Regts would have three Bns). This was supposedly to provide variance of roles in the Arms Plot and possibly move to each having four Coys (which would probably entail shorting home based Bns). However even with IRs and REDRUM personnel bringing units up to WE there was tens of thousands reservists with no roles. Again all before Wall Fall.
 
On the Artillery topic…
UK IRL
1989/90

105mm HE = 665493 (NATO SPG = 1440000; BAS/RARS = 865995)

155mm HE & Bomblet = 265710 (NATO SPG = 675000; BAS/RARS = 504330)

No NATO SPG listed and no BAS/RARS listed (203mm)

175mm (all natures) = 30340 (BAS/RARS = 86400)

203mm (all natures) = 5193

NATO Stock Planning Guidance …. What NATO thought you needed for a 30 day war


UK Battlefield Attrition Study/ Review of Ammunition Rates and Scales…. based on expenditures during the Yom Kippur War. What the UK thought you needed for 8 days of war at 100% strength and a further 2 days at 40 % strength

I don't know the exact methodology of the NATO SPG but it was to be for 30 days of combat. UK was based on 8 days of combat with everyone being at 100% strength each of those days (so it factored in losses and making good those losses) The last two days it was assumed that attrition would bring all formations to 40% of their authorized strength and there would be enough to sustain them at that strength for two days.......then there was nothing except sunshine.
 
According to its Wikipedia Article the British Army purchased 1,057 Alvis Stalwart High Mobility Load Carriers (HMLC) which were delivered 1963-71. That is 125 Mk1 ordered 1962 (delivered 1963-65) and 932 Mk2 (delivered 1966-1971). Its Wikipedia article also says that the Stalwart was adopted and entered service with the British Army in 1964 as a general transport truck in preference to the FV431, the load carrier variant of the FV430 series.

With hindsight, was FV431 the better choice? As far as I know the Stalwart did what it was designed to do, but it did need a lot of maintenance and all the vehicles were withdrawn in 1993. Meanwhile, the FV432 APC and its derivatives remained in service with the British Army to this very day.

I know that the Stalwart was developed (via the Salamander) from the Saladin armoured car and Saladin APC, but how many components did they actually have in common with the Stalwart? I'm asking the question because 1,057 FV431s instead of 1,057 Stalwarts would increase the number of FV430 vehicles built from about 3,000 to about 4,000 and as I'm a believer in economies of scale 1,057 FV431s might have been cheaper to build and operate than 1,057 Stalwarts.

However, I've also suggested that the British Army purchased the M113 family of vehicles instead of the FV430 family, in which case 1,057 M548s might have been cheaper to build and operate than 1,057 Stalwarts.

The M548 did serve in the British Army in the "Real World" because the Tracked Rapier was mounted on M548s, the M677 launcher for the Lance missile was based on the M548 and according to the Wikipedia article on the M548 the British Army used it as a logistical vehicle during the 1991 Gulf War. Therefore, 3 families of vehicle might have been reduced to one, i.e. the M113 family instead of the FV430 family, M113 family and Stalwart.
You're forgetting a couple of points.
Firstly, ignore anything you read on Wikipedia because the original entries are usually very wrong - with any attempts to correct them being deleted because the Wiki keyboard warriors would rather believe myths and incorrect articles on websites like Trucksplanet.com, Thinkdefence.co.uk - which they think are official sites.

With regards to FV430 series still being in service whilst Stalwart was sold off in 1993, remember that the FV430 series had the K60 multifuel engine fitted because of the fires, and then a true diesel for the upgrade to Bulldog.
The original FV430s had the Rolls-Royce 8 cylinder petrol engine, the same as the Saladin, Saracen, Salamander and Stalwart. The Rolls petrol engine was the British Army's engine of choice back in the 50s and 60s, hence why the early Army Land Rovers had RR B40 engines in them.
In 1993 the Army sold off a load of petrol engine vehicles, including the Saladin, Saracen, Humber pig, etc.

The Stalwart's swim gear was ordered to be removed in 1983 because of advances in Military Bridging, and the issue of Engineer support to find suitable places for trucks to enter and exit the river.

This video explains why the Stalwart was chosen over the FV421 and FV431

No, not instead of the CVR(T)s. One exception would be the FV103 Spartan which had dubious utility as an APC.
...
You're aware that Spartan was a NBC proof CVR(T) reconnaissance vehicle, compared to the Ferret being a non NBC proof CVR(W) reconnaissance vehicle.
Spartan used in the Royal Engineers of BAOR for Field troop commanders, Staff Sergeants and Reccy Sergeants. FV432s used as section vehicles
 
Firstly, ignore anything you read on Wikipedia because the original entries are usually very wrong - with any attempts to correct them being deleted because the Wiki keyboard warriors would rather believe myths and incorrect articles on websites like Trucksplanet.com, Thinkdefence.co.uk - which they think are official sites.
The trouble with Wikipedia is that, as a matter of policy, they don't accept primary sources or 'original research' - which seems to include looking at actual evidence. There are generally good reasons for this, but they break down when it comes to subjects that aren't extensively covered by informed secondary sources.
 
However, if standardisation had been taken to it's logical conclusion the British Army would have bought:
  • Leopard 1 or M60 instead of Chieftain.
  • M1 Abrams or Leopard 2 instead of Challenger 1 and Challenger 2.
  • Bradley instead of Warrior.
If I may, the Bradley IFV was far from standardisation, given, until very resently, the Bradley was not adopted by any other NATO country, given that the Bradley was overly expensive to purchase and maintain, and complex. If they had already built and operated the M113 APC, then I would suggest they license build and operate AIFV/
YPR-765 [preferably a stretched six-wheel derivative].

I can't argue about the British Army using Leo2's instead of the Challenger 2. Again, until very recently, the M1 Abrams was far from standardisation, given that no other NATO country used the Abrams.

Pioneer
 
Chally 2 competed with Leo 2 & M1A1 to replace Chieftains. Internal RAC memos indicated that if they picked Leo 2 or M1A1 they would be able to bring either into service/equip Regts faster because they could piggy back off the Bundeswehr/U.S. Army training systems. The general consensus was that M1A1 was the most preferable out of the two because of the volume the U.S. could produce and supply replacements/mechanical items. However there was a worry of the amount of logistics that would be needed due to the thirsty-ness of the engine. The drawback of Leo 2 was the main factory was about 48 hours away from being overrun by a Soviet Front. Ultimately it was politics, did the country who invented the Tank want to go out of the MBT business and lose jobs and perhaps overseas sales (which didn’t materialize except for Oman).
From what I have read the Vickers Mk.7, KM chassis with a Vickers Valiant turret was an excellent MBT and would have been in the running but KM would not give Vickers the rights to be able to sell overseas and the MOD did not want to be beholden to the FRG with a MBT.
