Okay first wave...

Here are the first ones submitted (Blogger only lets me put in five per post):

Courtesy of Sp4rki, a lesson on how to use your weapon.

From Mark, we have a situation I'm all too familiar with...

From anonymous, a very...um...original piece.

From Hypnotoad, a look at The Storm, a dangerous place for marines.

From Stix, a wonderful kick to the face.
