I remember running into the old version of these super early in my little IT life, back when I was just at AIT; All that time playing with FCBC2's and Blue Force trackers ended up giving me an addiction to very graphically boring military simulation games, but I'm not complaining.

We also used to run HMMWVs over them on my deployments, mostly to prove points and win bets lol. That got stopped after an MRAP crushed one though - The rakkasans who know, know ;)
