Much like in real life, Airsoft CQB, or close quarters combat, is a completely different ball game. You’re in much tighter quarters. Therefore, your movements and your gear are gonna have to reflect in correspondence to that. As far as movement goes, you need to watch your step. Because, since you’re gonna be inside, there’s gonna be BBs on the ground, and it’s a lot easier to slip on those inside. Something else to remember, is, since it’s such tight quarters, you’re gonna be coming around a corner. And most likely, you’re gonna be staring in the face of an enemy. When you come around a corner, you need to keep your gun tight, yourself tight.
