British
HQ Glider
Suggestion:
Allow glider to be dropped in Base sector
Change crew of team weapons to Commandos
Replace the stat of ATG with a copy of USF ATG (although the ATG used had the MK III carriage and the model can not probably be modified)
Maybe change the commando squad with a 4 men squad with rifles bren and not camo as a long range elite infatry to reduce overlap with Commando regiment.
OR simply move the glider to Commando regiment replacing either smoke raid operation or assault that might prove problematic with the new moving accuracy of tommies.
I think italicized suggestion would be a good idea to prevent Vanguard from becoming a no-brain doctrine pick like some other factions have. It already has UKF's heavy, a very strong off-map and their strongest infantry that was previously only balanced by cost. Removing camo and turning the glider squad into some long range specialist squad would keep Commando Doctrine's niche, as long as said squad isn't too spammable.
