"Crusader" Self-Propelled Howitzer I built this Crusader self-propelled howitzer as a birthday present for a friend who works on the development team at United Defense for the real thing (a modern replacement for the M-109 self-propelled howitzer). I was working from tiny images from the company's web site and apparently was able to get it more or less right (with the exception of the offset location of the 50-Cal. machine gun, which is supposed to be centered on the turret roof). You can visit the official web site and make your own comparison here: http://www.teamcrusader.com/
