Oh, kind of like an all-terrain truck with tracks instead of wheels. I bet their heavier than a truck. But, regarding goomohn's post some weapon systems have a greater range than the same weapon system from another country, and because of Fog of War you won't be able to see enemy unit capablities. I'm not sure that's what is happening, but you could play the other side and tell for sure. Even if I'm wrong, one of the possibilities would be eliminated, thus gaining more knowledge of the problem. I'm sure it's something logical.
