You know how easy it is to drop stuff? Well, then you know what these guys feel like who just accidentally dropped a 4-ton howitzer at Camp Grayling.

Camp Grayling is a huge National Guard facility towards the upper end of Michigan's lower peninsula. Everyone in Michigan who goes "up north" on the weekends knows about it because of the huge convoys of olive drab vehicles going to and fro near by.

Watch for Falling Howitzers!

A spokesman says no one was injured but did not say how the Howitzer reacted to being dropped 700 feet.
