The major isnt the tech structure, thats actually in the pizza base. You dont build units from the major, captain lieut... and yes, if thats destroyed you shouldnt be able to call in a Pershing. Not that it matters, cause its game over anyways when youre opponent is in your base.
Youre right, faction design is OKW ability to build Tech structures on the battlefield.
Consistency thru all factions would be to be able to get rewarded if your risky move, like foward t4, works and that you get punished when not.
