Yesterday I've played QB and My T-72B3 was frontally engaged by Bradley with it's 25mm gun. Bradley achived penetration in "upper hull" and killed driver. Crew dismounted in haste, but when it reoccupied tank later nothing was damaged and tank was brought back to action.
Actually, I was surprised that 25mm achieved frontal penetation. Is there any good map of weak spots as they are modelled in game?
