UKF as a faction struggles earlier on in the game but is a force to be reckoned with later on.
Tanks: Your armour is the best in the game if used correctly. I'll normally get an AEC for countering light vehicles first. Then a Cromwell but if I'm winning ill get a centaur to close the game. Then likely a firefly which has massive range. Situation dependent I'll go for a Churchill. The Churchill has the biggest health of any tank in the game so is great for sinking shots while the firefly removes OKW panther/tigers.
Infantry: Infantry Sections(IS) are arguably the best mainline infantry in the late game. They need to have 5 man squads, grenades and bren guns. They also have cover bonuses so need to have cover to be effective (ideally green cover). An IS with brens in green cover will reliably beat fallscrimjager in green cover. The sniper is powerful too but is hard to use.
Because your infantry requires cover build trenches/sandbags to defend your cut-offs. If in the right positions these will repel infantry pushes effectively.
If the fallscrimjager are behind your lines, cutting you off send your tanks and place your infantry on their retreat path. Grenade the retreating squad They will lose 440 manpower.
If you held the map, OKW would not have had fuel. Because of this getting a centaur would have won you the game. The centaur has insane damage against infantry and can kill rackettens with some luck. It cannot damage tanks though which is why it's not good in an even game.
Mines win games, Use them.
Overall UKF is not an easy faction to play but it is effective for more experienced players. In contrast, OKW is effective with simple blobs so is good for noobs. Because of this, you need to expect to lose brit games initially while you work the game out. Good Luck and Have fun!
Thanks for the reply, I guess I should use the centaur more.
As for the cut-off trenches, should they be constantly garrisoned or should I garrison them only when the cut-off happens?
One more question, what would be the best way to deal with indirect fire and MGs early on?
I use mobile assault so dealing with mortars isn't as painful, but I'm lost on how to deal with mg garrisons, I often use UC with WASP but it dies within two faust shots so I'm not sure if it's worth it. I've been thinking about using tactical support regiment commander for mortars, not sure if it'll work out though.
