Blue Five was a UNSC squad of five Scorpion Tanks at the Harvest campaign. The squad was traveling across a frozen landscape when it was joined by Blue Six, a squad of four LAAG Warthogs and two turretless Warthogs. The two squads then proceeded to the last known position of a recon patrol, which had come under attack by Covenant forces.
