Against Drones
Automatic weapons are the best.

Against Grunts

 * Anything. Except Grenades.
 * Alternatively, use precision weapons like the Battle rifle, Covenant Carbine, or DMR to headshot the Grunt. (Save the Needle rifle for bigger threats, like the Brutes.) This takes practice, but it definitely worths the time. By using precision weapons, you save not only time and your precision weapon's ammo, but also ammo for your automatic weapon to drain Elite/Brute's energy shields. Hope this helps. — S331  Bubbleshieldhud.svg(COM • Mission Log • Profile) 06:49, 7 December 2011 (EST)

Against Hunters
Try to hit the exposed area in the Hunter's back, joints, or neck. This will reasult in more damage, and will make the firefight be less dangerous. Also, snipe from afar and shoot when the Hunter is charging its cannon. This can stun the creature and prevent it from shooting. This could save your life.

Legendary In General
Be Careful. Don't rush straight into battle. Take time. The longer it takes to line up a head-shot means the longer you will live.
