Spartans are trained to use any weapon found on the battlefield — Human or otherwise. This training and philosophy means that resupply is always just one victory away. Efficient and deadly, Spartans often look at opposing forces as a kind of mobile weapons cache.

Offers a defensive property, allowing you to bat projectiles away with a simple swing. What you miss, the force of gravity caused by the swing is likely to hit. It can actually deflect rockets if timed correctly.

'''Covenant'''
==Support weapons==
Brute Mauler: a Heavy Duty large-barraled pistol used by Brutes. It can be dual-wielded.
Halo 3 introduces the idea of Support weapons, large weapons that require the player to be controlled in third-person view. Players cannot melee, nor throw grenades while using these weapons. A turret is typically activated by pressing {{xbox|RB}}. A Spartan, however, is strong enough to tear off these weapons (press {{xbox|B}} while using the turret) and use them almost like rifles. When detached, these weapons have limited ammunition capacity.
Brute Spiker: The Covenant equivlent to the UNSC SMG, a fast shooting dual-wieldable gun.
{| {{prettytable}}
Gravity Hammer: A large non-ranged weapon that can deflect large projectiles, such as rockets, grenades, and veichles, and do massive meele damage.
|- style="background-color:#dcdfe4;" cellspacing="0" border="1"
| <span id="Machine Gun">{{h3|Machine Gun}}</span>
|
|- style="background-color:#ffffff;"
| [[File:Halo3-HeavyMachineGun.png|150px]]
* '''AIE-486H'''
* 200 Rounds/Belt
| A Spartan is easily strong enough to remove, or more accurately, rip a turret-mounted machine gun from its tripod base. Although doing so will detach it from its main ammo feed, a Spartan can use whatever is left attached to the gun to devastating effect. It’s heavy even for a Spartan, and slow to spin up to full firing rate. It's more effective against flesh than shields.
|- style="background-color:#dcdfe4;"
| <span id="Plasma Cannon">{{h3|Plasma Cannon}}</span>
|
|- style="background-color:#ffffff;"
|
* '''Type-52 Automatic'''<br/>'''Plasma Cannon'''
* 200 Shots/Charge
| Very similar to the above machine gun, shooting plasma rounds instead of bullets. Better at stripping shields off the opponent, but not as good against flesh.
|- style="background-color:#dcdfe4;"
| <span id="Missile Pod">{{h3|Missile Pod}}</span>
|
|- style="background-color:#ffffff;"
| [[File:Halo3-MissilePod.png|150px]]
* '''LAU-65D'''
* 8 Guided Missiles/Charger
| Great for taking down vehicles quickly. The missiles are equipped with a homing beacon allowing them to change direction in the air to follow their originally intended target. The missiles will also explode after a set amount of time. The enemy will, however, hear a beeping noise when the missile is locked on.
|- style="background-color:#dcdfe4;"
| <span id="Flame Thrower">{{h3|Flame Thrower}}</span>
|
|- style="background-color:#ffffff;"
| [[File:Halo3-FlameThrower.png|150px]]
* '''M7057 DP'''
* 100 oz/Charger
| The M7057 is a standard chemical flamethrower, which projects and ignites a stream of volatile, semi-liquid fuel.
|}


'''UNSC'''
==Other weapons==
Assult Rifle: Returning from Halo: Combat Evolved, does slightly more damaged, but its' rounds are much smaller.
These objects can be used in melee attacks. Note that these weapon will kill anyone instantly and are used mostly in multi-player modes, aside from the hidden skulls in campaign mode. To pick these up, hold {{xbox|RB}}. To attack, press {{xbox|B}}.
Spartan Laser: A large, charge-up laser weapon. It must be fully charge in order to shoot. It has very small cartiages, but can destory entire veichles in one shot if aimed correctly.

|

Machine Gun: A very large machine gun weapon. Must be removed from a turret.
Flame Thrower: A flame thrower that can torch opponents or set ground on fire.

Plasma Grenade: No longer solid blue, not as adhesive as in previous games.
Spike Grenade: Looks like German grenades used in World War II, will stick to any surface.
Firebomb Grenade: Does not do any damage, but creates a large flash that blinds all players within blast radius for several seconds, allow the person who through the grenade to get several shots in without his opponent knowing his location.

  • AIE-486H
  • 200 Rounds/Belt
A Spartan is easily strong enough to remove, or more accurately, rip a turret-mounted machine gun from its tripod base. Although doing so will detach it from its main ammo feed, a Spartan can use whatever is left attached to the gun to devastating effect. It’s heavy even for a Spartan, and slow to spin up to full firing rate. It's more effective against flesh than shields.
Plasma Cannon
  • Type-52 Automatic
    Plasma Cannon
  • 200 Shots/Charge
Very similar to the above machine gun, shooting plasma rounds instead of bullets. Better at stripping shields off the opponent, but not as good against flesh.
Missile Pod

  • LAU-65D
  • 8 Guided Missiles/Charger
Great for taking down vehicles quickly. The missiles are equipped with a homing beacon allowing them to change direction in the air to follow their originally intended target. The missiles will also explode after a set amount of time. The enemy will, however, hear a beeping noise when the missile is locked on.
Flame Thrower

  • M7057 DP
