Because remote operation is generally bad and needs to be avoided wherever possible?
Normal HF-UHF isn't terribly useful for battlefield control of robotic systems beyond a few kilometers at most. Usually less, so we're quite literally still at teletank levels of autonomy for a remotely operated ground vehicle in a seriously contested EW environment, at least until autonomic control systems become sufficiently matured.
However, Starlink and other SHF/EHF SATCOMs are incredibly tough to jam, find, and intercept in general. Which means they're the only viable communication method. But that means SATCOM for at least every vehicle, but not every soldier. Naturally, America can't afford it at the moment, and FCS merely wanted enough bandwidth for every ground vehicle and NCO in a brigade, so it'll be a long time before we get enough bandwidth for every soldier, robot or human.
Weird statement, considering it was a recommended field modification taught in the Red Army, which was probably the most mechanized and most sophisticated ground force, at least in its ability to switch from high intensity mechanized combat to post-industrial, post-nuclear combat. It's not much different than the US Army teaching GI Joe to slap wooden pallets and tarps over the M1's blown out ammo hatches, but probably more sustainable, and definitely more common knowledge.

I'll apologize in advance for the topwar.ru article (lol) but it has a good picture of the O-832 rounds.
This is just what combat looks like after the PGMs get used up and the fancy planes get shot up.
At some point you have to rely on good, old fashioned grit and mettle, which means strapping O-832Ds to a PG-7V motor, with funny machined aluminum adapters you made on a lathe in a shed in between getting bombed by howitzers.
The main reason it keeps showing up in Ukraine is because there simply aren't many tanks to shoot at, and the RPG-7 is terrible at indirect fire with the HEAT rounds, while the OG-7 is barely used by anyone. On the other hand, the O-832 is just everywhere, and the modification is really simple, so it's a natural fit. It's also better than the crummy HEDP round.
GEN P.F. Gorman had a neat idea that you could give Joes a RFID or microchip like a SIM card, held on their dogtag chain, that is read by the exoskeleton's computer and holds your personal gait profile for the battle armor to predict your movements.
