Halo 3 Sniper-Spotter

Spotters for snipers are ridiculously useful. They can help you fend off unexpected attackers, pick off targets, locate enemy snipers, and protect you while you get ammo. Spotters should be well armed. That is, armed for any situation. Spotters generally carry a BR (Battle Rifle) and a shotgun or SMG. Spotters should have plenty of grenades and should not be in their scope at all times. The spotter for a sniper should be well versed in hand to hand, grenade placement (sticks), and should have good sense on where everything is in the battle field. If you choose to be a spotter, you too should go into forge and find good sniping spots and where ammo and grenades are.
First off, the spotter should be able to stick an enemy. If the spotter can't defeat the enemy than the plasma or spiker grenade will kill the enemy before it gets to the sniper. If you aren't good at beat downs and assassinations, be good and grenade throws and sticks. This will ensure that you become a wanted spotter. If you can easily stick an enemy vehicle or enemy infantry that I would want you as my spotter.
The spotter should always watch for any target or potential threat. If I'm sniping, my spotter is constantly updating me on where the targets are and where the threats are. For example, lets say we're on Valhalla and I'm sniping. The spotter should be saying something like, "Two in man cannon, BR and SMG followed by a mongoose heading towards the turret. Watch the middle area, three friendlies rushing in. Spartan Laser spotted, first target." Something like that would be much appreciated if I was sniping. As you can see spotting isn't a pleasure cruse. Try using easy terms for enemies and locations on the map. Your sniper should know where every significant spot on every map is, so take advantage. Say turret, tower, anything like that, just don't confuse your sniper.
Choose weapons for the location. I say always have a BR handy because of its head shot ability and abundance of ammo. On some maps people prefer carbines, but I think that the BR has way more ammo. Also, the spotters second weapon should be a close range weapon like the SMG or shotgun. I prefer it if my spotter doesn't have a laser sword mostly because of the limit of slices, the rareness, and the limited range. You might be thinking that it has the same range as the shot gun, but really, the spray effect of the shotgun bullets still dose damage to a persons shield. Also, you can smack without using ammo.
Overall, the spotters impact on how the sniper operates is huge. Good spotter=good sniper=good team=intimidation for other players=KICKING NOOB ASS.
