Halo Flood 10

He checked his motion tracker, and realized that a pair of Covenant Banshees were practically on top of him. The alien aircraft boasted plasma cannon and fuel rod guns. Though not especially fast, they were still dangerous, especially against ground troops. Combined with air support, the Grunts and Elites that dropped from the fork-shaped alien troop carrier were a serious threat.

He steadied his aim and sighted on the nearest Banshee. Careful not to fire early, the Spartan waited for the Banshee to come within range, then squeezed the trigger. The first assault ship came straight at him, which made it relatively easy to stay on target. Bullet impacts sparked on the Banshee's hull as his ammo counter dwindled.

The ship shuddered as at least some of the armor-piercing rounds penetrated the fuselage, pulled up out of its dive, and started to trail smoke.-Chpt.2 pg.58

The Master Chief returned fire. Without pause, he
thumbed the magazine release and slammed a fresh
clip into the receiver. He crouched, searched the sky for targets, and spotted Banshee number one in the nick of time. He braced himself for another assault. The Spartan allowed the enemy aircraft to approach, took a slight lead, and squeezed the trigger again. The Covenant ship ran into the stream of bullets, exploded into flames, and slammed into the cliff wall.-Chpt.2 pg.59
