Sadly generals, or at least the high command, tend to fight the last war, and tend to be fairly conservative.
WW2 was a classic example. Every nation except the US still had bolt-action rifles as the standard infantry weapon, on the belief that giving every infantryman semi-auto was a waste of ammo/too expensive/too heavy on logistics. Also motorization was not appreciated until late in the war, even in the German army - which despite all the attention devoted to the panzer/panzergrenadier divisions, was maybe 20% motorized at its peak. Mostly their soldiers marched from place to place, or used rail.
There is kinda a reason for this, that there are counter examples were new tech wasn't all it was hyped to be. And until something is battle tested, its hard to say how it would perform. Like early in the Vietnam war, US infantrymen may have been better off with the old M1 garand, because early models of the M16 tended to jam in combat conditions.
