I remembered the video was an ACE driver or an M1 with a dozer blade, but yeah, it beats grenading and bayoneting them like some guys had to do. Granted, it might not matter much for the M1 since it has the Special Armor in the prow, but it is serious for a BMP, BTR, BMD, or T-72/-80/-90. So I do think Russia's emphasis on fire support for their tanks during trench assaults is more because their vehicles are thinly armored than anything else, tbh.
You'd have a fat minute and change to get in there and crush the other guys, with a tank that pulls M4 Sherman-like mobility and weighs near a hundred tons, at least these days. Good news is they probably won't have either PF98s or RPG-29s, bad news is you're slow so someone who does have it might get a shot off.
But anyway yes, digging deep is more important now than ever. Foxholes will have to be built like pillboxes or something equally silly, and tanks will wear hats to hide from the drones. They already do in Ukraine. That will be the case, at least until people can get a grapple on the drone situation, and figure out when and if they are being observed passively.
There are some weird things, like quantum radar principles, that can be used to determine if your radar is being sniffed out by REC, for instance. Presumably similar things could be done with visual information, since there are incredible tricks of light that can be done,
like imaging reconnaissance done through miles-thick clouds based on a photon bouncing off a person. The weirder quantum stuff is done with photon entanglement, while classic (non-quantum) is done with coded lasers. I don't know if this could be applied in reverse, but the Chinese are super interested in quantum entanglement systems for visual reconnaissance, so that might be a exploitable weakness in future multi- and hyperspectral observation equipment.
Something like that, or something like a very powerful satellite constellation that can see little tactical drones (they are growing metal, if only from mortar bombs) could help. Would probably need to be routed through a Tac Air Ops Center or whatever the AF calls it. Or maybe a more powerful version of the PSS-7 that can sniff out datalinks from a drone, tied to a C-UAS mount on a gun carrier or a trailer. Won't work if they use highly directional commos or SHF SATCOMs but whatever.
My point was more movement can be done only when not under observation, and as it stands a lot of guys won't know if they're under observation or not until the WLRs call incoming mortars, or until the shells start landing if they're in a bad place, and either way it's not a good place to be in. It's why trenches with thick dugouts and heavy reinforcement are a necessity in Ukraine, and will probably be a necessity in WW3, as armies will chew up their best stuff first, and start using stockpiles and older kit as it drags on.
No one really has the industry or economic potential anymore to drag out a WW2 style industrial war, except maybe the Chinese, tbh.
