No, I didn't serve in armoured brigade, and even if I did I wouldn't have seen any actual combat. I know it's not the same thing but I have been TC in virtual battles and know that engagements can be pretty hectic (especially if we're playing WW2 mod). Still, I have always tried to maintain situational awareness, especially if friendly infantry is closeby. Time to time they have shouted to me if I'm unbuttoned. Arma 2 + invasion 44 mod rocks.
