This was mentioned awhile ago, but in combat, will lower ranks have less access to tech levels?
eg,
Ranks 1 and 2 --> tech 1 only
Ranks 2 and 3 --> techs 1 and 2
Ranks 4 and 5 --> tech 1, 2 and 3, but no arty/nukes/gates
Rank 6 --> all tech 1, 2 and 3
Rank 7 and 8 --> all tech
I think it'd be pretty cool. Like in the first UEF mission in the supcom campaign, the Colonel says you can't build the tech 2 units, but you get to play with them.
