Also, why not have marines double as paratroopers?… 1 per strategic bomber, but both units must start in the same territory. In order to use paratroopers, there must be enemy unit/s on the targeted territory, and they must be supported by land units attacking from ground or by amphibious assault. Bombers used in this way surrender all attack capabilities for that turn, and they would be vulnerable to AA artillery before the drop.
This might be a good way to get a common tactical strategy into the game as well as giving more value to an infantry unit worth 5 IPCs, or if that’s too powerful… you could charge 6 for them. It would also go a lot further to justify adding a new unit like this to begin with… not that it needs more justification, but if only one unit is to be added… why not have it do more than just 1 thing. Another plus would be that it’s a great reason to finally bump strategic bombers to the 14 IPC value they should be at.
