Grenades and CQB
just wondering what the general rule is when it comes to grenades in most CQB / Buildings etc.?? For instance, there are 3 guys in a room or building. I toss in a thunder-B with the Pineapple shell...maybe some bbs and powder...are the dudes in the room/building automatically dead?? Just want to know before I put money into thunder-b's.
I especially want to know for my visit to Ultimate Airsoft over the Xmas break.
