The gun I mostly like and use in Halo 3 is Covenant Carbine.

Unlike the Battle Rifle, the Carbine has seen few changes since Halo 2. It remains a powerful and accurate semiautomatic weapon with a moderately-sized clip. Because of the changes made to the Battle Rifle however, the Carbine is now far more accurate than its human counterpart, and is rapidly overcoming the second-class status it had in Halo 2.

I forgot what it's called as I only played Halo 3, it's the OP as hell sword.

That Sniper Rifle. It's 100% accurate unlike in CoD.

I don't think the DMR existed in Halo 3. It existed in Halo Reach, and Halo 4.

My favorite weapon is sniper and the Rocket Launcher.. reasons: Because I love to blow shit up and as "Ocean" said The sniper is accurate. One hit kill to the head and 2 shots to anywhere in the body.

The Energy Sword was my favourite melee weapon, especially for use on Custom Games.

Obviously the battle rifle, yes.

Or the Energy Sword.

I'm going to go old school and say the SMG, dual-weilding those was dope.

[Flippy]

BR and Snipe but Sword for melee.
