Approach a Brute with a charged Plasma Pistol. You can do this one on Easy, and Kizingo Boulevard is perfect due to its high number of Brutes. My Clothes! (5) (Plasma Pistol Overcharge and quickly kill 10 Brutes)
Shoot a Brute in a cycle from close range, then approach him as he just sits there and melee him in the face. When you come to the area with the overturned warthog and ample Brutes on vehicles, grab a Plasma Pistol from a nearby Grunt and charge it up. Switch to Easy to make this Achievement a breeze. The best place to get this one is at the Uplift Reserve. Stunning! (5) (Stop a vehicle with an overcharged Plasma Pistol and quickly kill the driver)
Make sure you have a gunner as well and, with some clever driving, you can get though the level without firing a shot! You may die as many times as you want. On Uplift Reserve, at the first Warthog Area, enter a Hog and give a soldier in the passenger seat your Spartan Laser.
