I'd go straight for an aerial strike - Hammer of Dawn will burn straight through plate mail, and kill them all instantly. An MAC round will do a hell of a lot of damage and with probably ten or twenty rounds, not to mention a hell of a load of Shiva nukes, Archer missiles and the promise of ODST backup on the way, I'd be pretty safe. And an MAC round could most likely render even Pandora pretty obsolete. Seriously, has anyone ever pitched a ten metre wide massively dense depleted uranium round travelling at close to the speed of light, against a box made of what looks like rock? Trust me, the uranium wins everytime.
TL;DR: MAC rounds, Shiva nuclear warheads and Archer missiles. Halo FTW ;D
