As Dan said, the muddy tracks look the part. However ( that most hated word next to 'BUT'), I think you need to add fine thread to tie down your stowage. Judging by your stowage rails on the turret this should be easy enough for you. It just adds a sense of reality to a model.(I've never served in the military, 'however', I can imagine wanting to find my tent and rations where I put them before the driving started!

Well done,
Matt
