I'm having a tough time fighting off double kubel opens and aggressive okw infantry. Any tips, tricks, or advice would be much appreciated.

I'll let one of the strategists do a replay review. Here are my two cents.
VS Kubel:
Since you didn't have the WC51 in your loadout, RE's are better than rifles to start. They have a better cost to damage early. Then upgrade to racks and get zooks on REs. Save the rifflemen's slots for bars. Stick to green cover or buildings early as the kubels will do much less damage. Then tech to M20, AA or .50 cals depending on the situation. Going for M10 or airbourne are the 2nd & 3rd best docs vs Kubel spam imo. Transitioning from the kubels to the luchs is where most players drop but you handled it well so kudos.
On Halbe:
Stick to cover as best as possible. The middle of the map is a negative cover death trap. Too many times you chased into it only to lose models or squads. Other mistakes include waiting over 5min to capture a fuel, getting both an AT gun and a Stuart (choose one) and 2 squads of rangers. I suggest paratroops for elite long range infantry on that map.
good luck
