Halo 4 offers players who rack up kills without dying the opportunity to call in special Ordinance Drops that can significantly turn the tide in battle. Knowing which of the three available choices is going to be most useful to you is key to making the most of the opportunity, while strategic placement is crucial to preventing your hard-earned power-up from falling into enemy hands.
For most new players the Personal Ordinance options like Speed Boost, Over Shield, and Damage Boost will only be marginally useful, but enemies won't be able to steal them when they inevitably kill you. If you want quick and easy stopping power, chose the most powerful weapon available to you; the Scattergun, Shotgun, and SAW Machine Gun all make excellent choices. Just be careful not to die before depleting the ammo as enemies can steal them if you fall.
