What is almost more important that destroying the tanks, is finding them in the first place. Half of any battle, land, sea, or air, is recon. If you can find the enemy early, you can dig trenches, prepare defenses, lay AT mines, and ready Artillery. Recon is the job of the M3 scout car, and as a scout car it is armored and carries a few machine guns. It can also carry a few soldiers for on foot recon. In US TD divisions M3 scout cars were attached to serve as recon for the force.
