because he said unsc vs unsc i assume he means 1s, for 2s/3s simple: 6 summits-banchees or 6 halls-hunters-or sui grunts-or brutes-or locusts,have unsc dbomb covy army,slaughter cobras/wolves in your way, bring in the vultures…played a turtle against 35s the other day…got bored because they chose not to attack(we were the turtlers supposedly being 2x cutter arbi vs 2x anders forge on dean…
despite 40 wolverines and 2 cryos when i got bored, using 6 summit banchees i managed to take a player out of the game, just dodge the wolves, if they sit to defend kill something else,cryos only come back every minute and you have 6 summits plus whatever your team does
really depends on the map but…i will just give a guide for unsc in general:
16 marines, 6 cobras(3 spartans in cobras) 3 vultures…
use marines/vultures/leader powers to kill their front cobras, use your non spartan cobras to test their range and move spartan cobras just outside of their range, rinse and repeat until you start hitting their base…forge is worst in this situation because of his leader power…macs can easily soften up for a small move up as well as having odst and a cryo can give you time to move up, lock down and kill before freeze ends
keep in mind there are some maps that work better then others…
chasms is okay because of all the different approaches but if he gets reinforcements up its going to be extrememly difficult to advance
gulch has a wide area to advance on so you can find the weakest spot to attack with a scout
pirth…this map is a NIGHTMARE with only two ways to their base, both being choke points and both being right next to each other its easy to block air and vehicles…if you arent cutter on this one expect the game to take at least 25-30 minutes using the above method to break through…if it is even possible
release: easy stuff: get both flood hooks, release flood on your units consistantly, go for 3 13 star tanks, 5 3 star vultulres, make a bunch of air pads… charge base, cani+leader power+barrage=insta base kill…spam hornets/hawks/odst to keep base from building for 1 minute, gg
tundra: not as easy as release but still not very difficult, use mega turret/ above advancing method to inch up on their base
barrens: there is flood EVERYWHERE on this map, kill them, get stars on a spartan cobra, should get 12 stars at least(counting flood stalks)
advance with above method, yes there is only one way in for vehicles but with the extra veterancy you should be able to inch up at a decent pace
blood river:6 vultures,2 hornets, find wolverine weak point, charge air through it…cobras cant shoot up so if you cant kill the base like this…your probably f’d,
only suggestion: 6 air pads in close base, barrage his base, move in 4 marines to his base as last vulture dies, dbomb heal while queing up 6 vultures giving you 2 shots to kill the base, this doesn’t work you’ve got no chance,cobras cant shoot up and so cant be used
