I am thinking of adding a third research table to our G40 games. I believe one or more might have been suggested already.
1. Self-Propelled Artillery Artillery can move 2 spaces and can blitz when paired with tanks. Infantry and mechanized infantry paired 1:1 with SPA attack at 2.
2. Super Carrier Aircraft Carriers can transport 3 aircraft (fighters and tactical bombers).
3. High Speed Transport Destroyers can transport 1 or 2 infantry
4. Convoy Escorts Enemy units disrupting convoys ignore roles of 3 or more.
5. Mine Layers Destroyers can lay mines instead of moving, attacking or defending. Anti-Submarine rules are not applicable when laying mines. SZ that is mined do not impact friendly units. Enemy units entering a mined SZ roll 1d for each ship. Each ship that rolls a 6 is hit by a mine. Aircraft on carries that hit a mine can fly to a friendly territory or carrier up to 5 spaces away; if there are no applicable territories or carriers then aircraft are lost. Mined SZ is cleared after enemy contact.
6. Improved Transports Transports can carry 2 infantry plus one additional ground unit
