As mentioned, no replay, no great help but...
Against OKW its generally a good idea to go sniper, they dont really have much of an easy way to counter(Fuck you LEIGS)it directly so when they are dug in you can pick them off at a distance and move your tommies in, later game the sniper comes into great use by dropping expensive obers or falls and getting rid of them from the fight. Hell, with its stun shot it can even protect itself against the heaviest of tanks.
In 2v2 you need a mortar pit, its upto you and the map as to where and how agressive you place it but the amount of bleed it causes the enemy along with the amount of agro it draws in can pull the enemy from their defensive positions almost instantly.
Again with OKW you have to remember that they can't counter MG's other than a flank of course until they get their first tech structure up so it is generally a good idea to build a vickers first to claim important buildings.
Doctrines is another one, if you are a pre made team its usually best not to both be the same faction, look at the recent 2v2 tournament we had, I dont think anyone went double whatever because if that faction has a weakness, it has double the weakness. That said however, if you insist on both going UKF you need to make sure that your doctrines compliment each other and fill the gaps that need plugging such as CQC units, mortars, AI LV's so on and so forth.
Post a replay next time and people will watch it and give you tips.
Thanks for your reply, I posted the replay.
One note -- if you see the replay, you can see that I never had the chance to put the mortar pit down. I think it would have gotten overwhelmed the moment it went down, even if I was stable enough to put it down.
