What all that can make me better at playing smarter at Halo: Reach?

To begin with try to space out your shots with weapons like the DMR or needle rifle (practice using each weapon in custom games and forge, it really helps). Secondly don't get to attached to one armor ability it's good to Know what situations each one is good for (recommended 1.sprint, 2.invisibility 3.evade 4. drop shield 5. hologram 6. armor lock.). Also don't chuck a grenade every time you see someone its annoying and a waste of ammo ( practice grenade sticks in forge or custom games.) they should be used when an enemy goes into cover and has low Shields or if you can 100% stick'em. Have Fun. If you need help/ more tips contact TubanATOr44568 on XBOX live. :)
