[Airborne Butters]

Actually I'd post it in offtopic or history

But back to the topic, the Marines actually modified theres. This could have caused the problem with it 'jumping foward'. But it still did jump foward a little. If you ever look at the bars in the filed, Soliders often fired them a point down to the ground just a little, so when they jumped foward they'd point more straight. Also notice how the mono-pods were more 'skid feet' rather than 'spike feet'.
