This is if you want to get blitz medal easily on normal as the us. i dont know the name of the map but it has a river extending from the north-east corner to the south-west corner of the map with two bridges and 3 oil dereks on each side.have the existing dozer make a power plant as two more dozers are building.
the dozer should be done right before the power plant then continue logicaly until you have a barracks. have your third dozer build a patriot missle near the front of your base and train 3 rangers and 5 rocket soldiers and 1 extra helicopter. then have it carry your soldiers across the river.let it hover for a while. if your figfhting china they will make 7 or 8 red gaurds and send them to your base, but will be killed by the lone patriot missle acompanied by a dozer for repairs. land near the enemies northern supply pile.the us rocket soldiers are by far the best rocket soldiers (in my view) because of their laser sights. the rangers are for the sole purpose of protecting the rocket guys. if you combat drop them then only the rangers will come out and can clear an LZ and take fire off the chopper. then drop off the rocket guys and send your chopper back and fill it with more guys that you've been traing (if needed). then first kill the barracks, then war factory, then it doesn't matter. normal China will make an air field but no migs until much later, so you can save that for last. tyhe laser sights can kill any vehicle in a few seconds, but if don't babysit your soldiers, 1 drgon tank or toxin tractor will kill them all and its all over. for me, its easier with china because they dont make air defense in normal.
