this kit is very simple and has good details. The tracks are 1 piece the suspension arm is the only add on to the tracks and that is only 2 pieces. The cab is 1 piece but has no clear plastic for the windows. The interior is only 3 parts The dash a divider and the control sticks. The cargo bed has only 2 extra parts. The cab and bed mount very easily to the chassis. The only down side was the tow hitch which doesn't really allow the 155mm cannon to hook up well. There are a good set of decals that go on well the top star had a problem due to a vent i just moved the star a little further forward where the plastic is smooth.
