Long story short, I'm a new player and I suck.
I've been trying to follow the guide:
http://www.coh2.org/guides/21246/okw-special-operations-double-agent
And I'm getting success following exactly what the guide taught me to do fighting against USF and SUs.
Usually I follow strictly the guide's build order.
(3 Volks, Mechanized, AT Gun, 4th Volk, Stuka/Puma, Stuka/Puma, PSchreks, Hospital and ISG and finally Obersoldaten, and your usual tanks.)
Usually I rush and stomp the opposition in the early game (Sturms OPOP), cap with Volks and slowly suffer for the mid transition, and then bring out the big guns to seal the deal.
But as the UKFs was released, I find myself losing the eary game pretty consistently.
Green covered ISs and the flame-spitting car is just too much.
Vickers have a much larger arc than Maxims, and the 40mm just wrecks my Volks hard.
Sometimes I'm lucky enough to survive and still remain formidable in the mid. (Through mining, flanking, godlike Stukas etc.)
But when the British tanks hit the field, my Puma just can't fight them unlike T34s and Shermans.
Also Stuka barrages just does jack-all against them mortal pits, 40mms and AT Camps.
Let alone whatever units they've got wrecks even Obersoldatens.
When the JP4, P4 and Panther hits the field. It's usually too late.
So, what should I do against the Brits, and how do I plan my mid-game against USF and SUs?
