or if you have more income and a better pc, try the newer Men of war by best way. i can really vouch for the game, it is one of the few Rts' with a HUGE range of vehciles, Turtle, js2 , t34 Pioneer and Pz2 Luchs for examples ( in multiplayer)
the single player lasted me a good 2 months due to some missions being quite tricky, you can click to tell vehicles or troops where to go, or directly controlll them, driving them with the arrow keys and firing witgh the mouse, i cant tell you how much fun it is to drive a Kingtiger through a house
worth checking out.,
