New way of playing usf, on some maps?

this replay wasn't a very good example cause the okw player kinda dropped the ball hard. but the way you are thinking is right.

I got a good strategy this way, I call it the "bait and switch" strat.

1.start with one RET then one rifle
2.get the jeep and unleash hell
3.if you feel the okw is getting an AT then don't push it too hard and send the jeep away asap, then use the fuel to get ambo + 3rd rifle.
4. call capt, if you get luchs rushed then get one zook on each ret and the capt if you want. Then get one stuart.
5.(this is the tricky part) most okw players nowadays get a Puma as soon as they see the stuart. if the puma comes, send the stuart away and rush sherman.

the thing is tricking the player to waste resources on useless things like the early rak and puma.
after that you can have a few options, you can get 2 shermans to deal with the luchs/puma then send they back later to get 2 scotts (excellent against raketen and volks/obers + the smoke barrage is awesome) and jacksons.

Pack howie is super expensive but damn good until you get your scotts.

Use recon pass to try to ambush his flaktruck on the 10 minute mark and before each assault to see where the invisible raks and MGs are then smoke and push.
