When people rage because you're "camping"

The difference between a camper and a sniper is that the latter is covering long range and keeping the enemy's head down, while the first is just a prick.

I call it an ambush

Snipers cannot run around like an assault force as we don't have the rate of fire or the time necessary to make accurate shots up close. Very few understand this, get all butt-hurt and call us "campers" (and far worse things) because we killed them legitimately, perhaps multiple times in succession because they gave us a clear shot. Learn the difference!
