My special ops days are far behind me, but for those of you still running game as a contractor for Mi6 or the CIA, you might want to take a look at the Battelle Tactical Air Initiated Launch system.
It uses compressed air to fire objects at up to 100 feet in distance and 60 feet high. A titanium grappling hook with a Kevlar line is just one of many objects that can be launched out of this apparatus; anything that can fit in its barrel is game, like t-shirts and other fun objects that are sure to assuage your enemies.
Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
