Try massing Cobras then, and slowly move them up while "attempting" to jack his cobras.
One of two things will happen:
1. Spartans die, but your cobras get locked down and start having an epic cobra war.
2. Some cobras die, but u get some cobras yourself, so it balances out.
3. You should be able to get at least 1 cobra if u do this right, so u will have a 2 cobra lead, and defeat his army.
Trust me, this will work if done right, plus, wolverines will do crap vs. your cobras.
Having 1 or 2 tanks isn't a bad idea to have if they got spartans too, hell, get flashbang and use those vs spartans if they have them
lol, me and Viobolo Bashing on some fine gentlemen.
