I've had issues with their midgame. It's basically non-existent.
Early game they're actually just fine, except against OKW. It doesn't take a genius to look at the graph of relative army strengths after playing a game as brits against OKW and seeing that from the very start OKW have an overall army value advantage, and unless a major mistake is made, the OKW will keep that advantage throughout.
Some key things I think give brits an edge:
- Versatile mines
The mines go off if anything runs into them, and generally cause engine damage. They're old fashioned mines and I think good players should lay more of them.
- Strong unit carrier
The bren carrier can take some punishment, but it suffers from the same problems that all light vehicles suffer from, which is easy infantry-based AT. Obviously not so good against Wehr, but decent against OKW. Bren in Bren, if you're willing to spend the fuel and munitions, is really good. Better than the armored car out of T2, I think.
- Bofors
Still a murder machine. I don't think I need to say much about this. I hope they keep it the way it is because as an emplacement, it's the only way I can see to reliably survive until late-game.
- late-game
Comet tank, Cromwell Conga Line, and Sherman firefly. Greatest armor in the game. If brits make it to the end, they do very well. Currently my strategy in 1v1 is similar to my strategy as soviets, but much more campy. Sitting on points, disrupting wherever possible, and surviving until I get the hard-hitting late tanks. OKW P4 is really good against cromwells tho, just something one should watch out for.
I'm still experimenting with the brits, most of these CoH2 factions aren't super-straightforward to me (see also: nothing like the PE) so I'm re-learning the game again. If anyone has any other constructive things to add regarding UKF strengths that'd be nice.
