Good weapon is irrelevant if the squad have THE most horrible veterancy in the game and is a 4 men squad going up against factions designed to kill 5-6 man squads.
Airlanding officer is beyond terrible combat unit and its abilities are the only reasons why you'd ever consider one.
non-doc and effected by 5man upgrade would be interesting to try out
Commandos is a far better CQC unit, 5 member and cloak.
Which they should be, so if you want the extra punch on a CQB map then you can go a doctrine with commandos. But giving UKF 1 non-doc cqb unit that can actually flank and kill stuff is needed here imo.
Brits have not been the same since the bren nerfs and something needs to budge
