For those of you who haven't seen it yet, this is a great show.
In "Lock n Load with R. Lee Ermey", Gunny traces, in his own unique and entertaining way, the development of various weapons (handguns, machine guns, etc.).
Ermey's obvious enthusiasm for the subject matter and the pleasure he gets out of not only talking about weapons but also shooting them elevates the show into "must see TV" status. Highly entertaining. Gunny is funny as Hell, and "Lock n Load" kicks butt.
New episodes air on Fridays at 9 Central on The History Channel.
Check it out if you haven't seen it already.
