What infantry overwatch for ATGMs that have a four klick range looks like is difficult to picture though. It may be a brave new world.Read a book called “Tip Of The Spear” about front line fighters in WWII. This topic was of substantial interest to me at the time as despite being Airborne & Ranger Infantry qualified, I was branched into Armored Cavalry.
Don’t recall the exact numbers but armor crewmen casualties were substantial, although lower than Infantry. But the forces had little success in getting Infantrymen to volunteer to become tank crewmen due primarily to fire. An infantryman might get shot or (more likely) get artillery dropped on him. But any Infantryman who had heard trapped crewmen screaming while a tank burned considered himself lucky.
One reason tanks are successful on the battlefield is precisely because the team must work together. Tank crews, whenever possible, are put together with extraordinary care, so that they will work well as a team.
The way Russian forces deployed tanks was badly flawed. Without Infantry to protect their flanks and blind spots, they were highly susceptible to ATGM fire.
ATGM’s have their own limitations, notably rate of fire.
It remains to be seen if the speed of western MBT’s over terrain, their accuracy and fire power, and superior communications, and superior ISR, and deployment as part of a combined arms team will result in more breakthroughs.
