I made a similar vehicle about two years ago. I used mudbox to paint the base for the camo pattern. Don't know much about Substance but you should be able to do it in that program afaik.

I can recommend Alec Moody's Bradley Vehicle texturing tutorial:  http://3dmotive.com/series/bradley-vehicle-texturing.html
It's for Photoshop but much of the general steps should still apply in Substance Painter.
As for your uv's. I think you could overlap some pieces that are only visible from one side at a time to get better pixel density out of it. You just have to pay special attention then painting on the camo so it matches on both sides without looking too obviously mirrored when seeing the vehicle from front or top.

wont overlapping uv cause problems when baking the normals ?

You can place duplicate uvs outside 0-1, bake, place them back. Or just bake and then duplicate the meshes and mirror them. Some uv flipping will be required.

You can detach one side of the overlapping geometry from the low poly and cage before baking, then reattach them to the model afterwards. Or what Musashidan said.
