It lasted long enough to take out 18 assorted vehicles (8 tanks) and 127 infantry! At the end of the game a company of infantry supported by a flame tank and several armoured vehicles were attacking it at close range. It was receiving close protection from a platoon of infantry and was being supported at distance by various light weapons. I don't have a problem about the AI not destroying it, although I do have a problem about the AI continually attacking a silent gun and losing it's chance to take the flags.
