1. Luftwaffe Dive-Bombers (revised)
Europe was blitzed and bombed. The Ju-87 Stuka dive-bomber, a small plane, played a big role. Its screaming siren generated terror on all battle fronts.
Your fighters may conduct first round tactical bombing runs. They are subject to antiaircraft fire as normal. In the first cycle of combat, if there are no defending fighters present, the fighters hit on a roll of 5 or less. In succeeding cycles of combat, the fighters hit normally. If defending fighters are present, this first cycle ability is cancelled.
2. Jagd Panzers (replace Luftwaffe Dive-Bombers)
The Germans put their early war experience into the development of tank destroyers. These armor roamed the battlefields to ambush enemy tanks - armed with more powerful guns than similar tanks.
Your tanks defends on a 4 (5 if you have the Heavy Tanks development)as long as the attacker has tanks in the battle.
