Watched it and here are a few tips:
You mainly lost because of your lack of counters. Don't go assgrens if you know you won't be able to bleed the enemy with them. You lost 2 models until you've reached close range, then retreated. Not really worthy. And then you started using them at long range. No.
Don't cap a point with 2 squads, 1 is more than enought to cap a point. You were just wasting time and fighting force, which you really needed.
Both of them were really, really static. Know the counters, get a mortar. Or in this case, 3-4 of them.
Also, against brits it is a MUST to have at least 1 sweeper on your pios.
Try to communicate with teammate because you were scattered most of the time, don't even knowing what the other's doing.
Try to get the best cover in every fight, but don't die for it. I mean, your troops were standing next to light/heavy cover. All you had to do is to order them to it, because it can matter. A lot.
ATGs are not frontline units. If you see that there are no supporting troops around it/ units that can screen for it, then just draw them back.
Also: Don't rely on StuGs and Paks on a map that greatly supports flanking as they are dead if somebody got in their back.
The commando squad with their gammon bomb at ~29 min was well deserved for a learning slap in a face. Why? You already knew about them, because they even threw a grenade at your ostwind. They can't magically disappear (nah, I'm not referring to camo, only to that they can't vanish from an area under 10 seconds). Also you don't repair that close to the frontline if it's constantly shifting. Even if it's feeling safe. It's not really. 400 MP down the drain. Still no sweeper upgrade, the second thing you want them is because as far as I remember, they grant a +33% repair speed bonus.
You should've gone T4 and brummbar as you hadn't gone for mortars and ostwinds are not that good against infantry.
Aside from that, I only checked your teammate a few times but you were much better at this than he was.
So to sum it up:
You needed mortars very badly and quickly because that could've punish static play really hard.
You were not fighting in the best conditions.
You need to identify the map's settings and adapt to it. Assgrens were sort of a good choice, but this map needs a lot of mortars and using Paks and assault guns other than middle is a very risky move.
Go for that T4! It's worth it now as brummbar's buffs actually made it a viable choice against infantry and emplacements and Panther is still a viable AT choice (even if it misses a lot thanks to the bad accuracy it's given).
Hope I pointed out a few things you couldn't watch out for
Good luck next time

You really threw away every single one of them
