I think all the complaints could be fixed by making retreating units stop further away from the base, and letting rear echelon troops build the weapon racks in the base sector.
I mean why is the M1919 rack even there? Only one of six commanders can even use it.
Good idea. Question is, should these racks be destroyable by enemy, and should rebuilding one cost only time or fuel and manpower too?
Also agree on m1919, it is there just to remind you of commander you might have not chosen. I´d really like smg (tommy or at least the grease gun) as a third non-doctrinal upgrade, seeing as it would add a new role for riflemen. Might mess up the balance though, and we already have thompson upgrade for vehicle crews for some reason so it would require some rethinking.
And +1 for OP.
