Assualt Rifle

Very effective, three shot burst, effective at close-to medium range's, very good combo to the MC6 Pistol.

Shotgun
Very Efective at short range, very deadly at CQB when a shot is fired and a melee immdietly follows, not very affective towards the flood.

Vehicles!

Worthog (Machinegun, Guass, Transport)

Mongoose

Scorpion

Hornet

Pelican

The Worthog has been around since Halo CE, It's the highlight Vehicle of the Halo series, it's fast, deadly, and flat out awsome, the worthog will be mounted with A machine gun, Gauss cannon, or nothing (worthless pile of crap)

Mongoose, it's pretty new, looks like a ATV but someone can piggy-back ride you, it's fast and light, very weak though, wouldn't recommend going into an enemy held position with this, unless you got a nuke on your chest then it's WWII all over again.

Scorpion, my fav vehicle on Halo3, it's slow but whoever said a turtle couldn't win the Olympics with a giant cannon on it's back? It can carry a gunner, and in campaign some guys who will ride on the treds.

Hornet, It's pretty awsome, you get a foward mountned machinegun and rockets, adn it flys. Whats not cool about that? It's got more armor than a Mongoose, less than a Scorpion. you'll encounter this in Forge, Multyplayer, Campaign, and Custom Games.

Pelican can't fly it, oh well. There's a way in Halo:Reach though!
