When I played my last game as soviets on the semoskyi summer I went like 3 shock squads (for lultz OFC). And then happened something really unexpected. I expected that those grenades are sh*tty and will deal litlle damage to units in garrison.
But these greandes did 0 damage to houses (no matter if it was small house, normal house or church). Units in the house were damaged, but the house itself wasn´t. Like if the grenade didn´t even exploded there.
Looks like shocks are worse than they´ve been before

I´m not good at making videos, so if someone (Smith) is interested, he´ll have to try it himself.
PS: I don´t know if this bug occurs on other maps as well, after this fiasco I said no, thanks, to shocks.
