What mode are you playing? I play team games so my advice will revolve around 2v2+
Typically go 3 IS, UC, 2 RE. Depending on the map and the game I will add an mg and/or add a sniper that replaces one of the REs. The starting build is also dependent on matchup. I would possibly skip the UC for an extra IS against ost while keeping the UC and maybe adding an MG against OKW. OKW has always been weak against early LVs such as the scout car. As such the UC is an important tool in holding off Volks/sturms early. Against OST IS can easily hold off Grens so the UC isn't needed to help IS as much early.
The AEC is good AT until mediums arrive. Even so the AEC can deal with mediums. The cromwell is essentially the medium tank aka same tier as Sherman/p4/t3476 for UKF and the comet is the premium medium tank aka same tier as t3485, E8, Sherman 76, Panther etc. The Comet is pretty bad right now however and I would not recommend getting it. The valentine is a replacement for the AEC, it has slightly less AT power for much better AI power.
The AT gun for Brits is really good. It also gets bonus accuracy against LVs which makes it pretty damn accurate against them. Also remember that REs have snares now which helps the AT gun a lot in securing kills or preventing circle strafing.
Croc is map dependent on its usefulness. If the map is close quartered and has lots of garrisons its great, on wide open maps its bad.
Double Sextons are viable in team games. This of course depends on how the game goes and if you need something to smash static defenses in the late game. Make sure either you or your teammate has proper at to defend the artillery.
Commandos I would limit to 1-2 squads. Anymore than that would cause severe bleed and pop issues. If you know for certain you are planning on going commandos I would recommend no more than 2-3 IS. 4 IS plus a commando squad is too much bleed.
Heres a small tip about picking between the cromwell and the centaur. If you have been ahead of the opponent most of the game and have superior income I would recommend the centaur. The centaur imo has better shock value so if you can get it before they can get a medium it can reek havoc on infantry squads. I'd also recommend the centaur if you have 1-2 at guns + AEC that can defend it. The cromwell is better if you know that the p4 is coming soon since atleast the cromwell can somewhat combat the p4.
Hey, thanks for replying to all my questions. This was the reply I was looking for. To begin with, I play 4v4 and 3v3 (preferrably 3v3). I plan to go down to 2v2 once I understand this faction better.
I do have a problem with population when I play UKF. I can't seem to properly form my army in the "right way" just like with Ostheer. I will try what you said, however I do NOT play without an MG. Never ever. It's one of my main counters to blobs and works wonders. Without it I would lost most of my games. So I can go 3IS, 2RE, 1 MG and UC is situational depending on OKW/OST.
The thing is you can always send the UC on a suicide mission if you don't want it taking up pop or w/e.
Anyhow, I have tried to play with only 1 Commando squad and I did not like it. I still made so much damage with them the last game. Wiping 5 team weapons, destroying a tank with a satchel and wiping countless squads. I feel like I need 2 commandos to accomplish my playstyle. I love to ambush and micro is not my problem. Likewise, I find that using the sniper in combination with commandos (if you can) is an absolute monster tactic. So for me Commandos are a must tbh..
I usually go AEC, I have learned that the AEC is a beast and I absolutely love it. The Comet has been dissappointing so I usually go Cromwell + Firefly. I will consider the Valentine from that one doctrine. Thank you.
I have had success with the AT gun. And I usually only use 1 though. What about using 2? Do you think that is ever viable? I tend to go for a AT emplacement if the enemy is super armoured. Tends to work.
The Sexton is something I've had success with, especially against OKW halftracks. It demolishes their ability to relax. And I will consider getting 2 of them in a team game where the rest of my team has proper AT/Tanks so I don't waste fuel.
The Centaur is something I hate to play against as Ostheer, it slaughters infantry so I prefer to go for a Centaur if I can. I'm just afraid of the enemy pulling out a PZIV/Stug and I have no tank power to compensate with. Also an Anti-Air the Centaur is good I hope?
Thanks again for the tips. I've noted some stuff down.
