DeEspona has a ton of military vehicles (Ships/Boats, Tanks, Jeeps, Aircraft) you name it, they've got it and ALL of them are EXCELLENT quality models. Unfortunately most of them are in 3ds/max, and Lightwave format, but I think a number of them have been converted to Poser over at Turbo Squid. Check it out... I'm sure you will find what you're looking for over there. Cheers! Pam
