Forum:Priority: Horizon

I am currently stuck on the section of the mission with the Brutes and the Banshee. I am playing as a Vanguard and my loadout out is as follows: Black Widow I, Geth Plasma Rifle V, M-9 Tempest V, and Heavy Claymore I and my squad consist of Garrus and James. I have no idea what goes wrong in the mission but the brutes keep destroying my team and I could really use some help here.
