User blog comment:Braden 0.0/What's the biggest mistake you've made in a Call of Duty game?/@comment-2033813-20100525172911

Couple things:

Dropping a Harrier Strike on myself (twice in one game!) on Highrise with Danger Close equipped. I went 14-2 in that game.

Deploying a Tactical Insertion right in front of oncoming enemies and spawning right in front of a claymore after getting killed the first time.

Jumping out of any high place forgetting that I did not have Commando Pro equipped.

Setting a Claymore/C4 trap and being too close to it, resulting in a suicide.
