SD:HS 129 B1 Tank Buster

 is a German Air unit.

Strategy

 * As far as tank busters go, the HS 129 is one of the most effective strike aircraft in its group. Although weaker than its younger brother, the B-3 and its 75mm cannon, the B1 can easily wreak havoc and destroy any enemy armored unit in phase A and remain a threat to others in subsequent phases. Buy one, keep one.
 * However, it needs either air superiority or heavy protection. It's not designed for dogfights and relatively slow, allowing enemy dogfighters to run it down with relative ease. At any rate, unless you are confident that you have control of the air, keep it closer to your side of the front and be ready to evacuate it at a moment's notice while deploying your own fighters to chase the enemy away.
