Watched it, not really much to say except "play more and improve your micro" you simply lack experience, which was expected. Dont leave armored cars near guards, don't setup MG42s when you see huge blob right in front of it, try to pay more attention to dying units.
You'd have it if not for micro and squad losses during multiple engagements at once.
Thats pretty much all I can tell you.
On a side note, doctrine choices of both players tell everything about how people see current balance
