uber anti tank units

[Ricky B]

2 abstractions are in play - not every man is represented in the game, such as most HQ manpower, supply troops, mechanics, etc. Possibly dedicated weapons in the pillbox also, part of the + factor the pillbox confers on the unit. Also, the unit isn't just an AT gun, but also other weapon equipped men from the unit. A German AT unit had its guns but also generally 1 LMG per AT gun also, at least that was authorized. So consider the pillbox held by maybe 20 men with the AT gun and at least 1 LMG, plus any dedicated troops for the fortification.

Ultimately, what you are seeing is that the defender can't "lose" the assault unless all its units disrupt, so a failure to disrupt means the defender will win, period, unless wiped out by assault losses, which are tough to inflict in a Pillbox.
