Had an airsoft war last weekend. First time, did pretty well.
I found out how undisciplined people can be, even when death isn't involved. Sure, an airsoft BB hurts, but as long as you're spraying them out at whoever's shooting you, it's worth it.
So me and a couple of people are holed up in a mock building; three stories, made up of stacked transportation containers. They ascend sort of like steps, except the only entrance is a set of stairs on the outside that goes to the second floor.
So we set up a great defense. I take the wooden covers off of the windows to use as cover, my friend opens a door behind some stairs and positions himself to shoot in between the stairs as the enemy comes in.
Then some dipshit on our team who was supposed to be with somebody else chickened out on his partner and pretty much just bitched at us.
I patrol around, continually reminding my way to tensed partner that he's covering the only way in, and they'll have to open the loud as fuck steel door to get in.
Once, I go outside, and see the enemy team stacked up on the stairs. I have a pissy ass single shot shotgun with an improvised magazine (Really fast shot velocity, though), so I take a shot and go back.
Of course, right when they're right where we can get them, Dipshit McPussy convinced my nervous partner to come up to the third floor, abandoning the perfect position he had. Other guys burst through the door, and we hole up on the third floor until we surrender. Fuck.
Of course, in another game, I kidnapped a person and used them as a human shield, since I didn't have a machine gun like half the people out there. Dipshit happens to be the guy behind the guy I nabbed, so when he's telling me to let him go, I pump my shotgun and give him a BB in the belly, and then ran my ass off. It felt so good.
