Desert Eagle

 * Magazine size: 8.
 * Total capacity: ??

RPG-7
The RPG has terrible accuracy but can be reloaded and recharged at ammo stations. When fired, it slowly arcs in a random direction. As such, projectiles may go above or below the intended destination. Also, the projectile is slow and you must lead your targets if more than about twenty feet away.

AT4-S
A bazooka-like rocket launcher that provides only one shot, but perfect accuracy.

Stinger
This is a one shot launcher that requires a lock-on before it can be fired (this means it can only be used on helicopters). To acquire a lock-on, simply aim at the target for a few seconds. During the process of locking-on, hold to make sure you automatically fire when ready.
 * Special Ops availability: Wetwork.

Javelin
The javelin is a highly technical rocket launcher. You must first aim and lock onto targets before firing. It can only aim at enemy helicopters or BT6's. To lock-on, you must aim at a target and hold them within the targeting reticule (the big white box) until the lock-on is complete.
 * Campaign availability: Loose Ends
 * Special Ops availability: N/A.

When firing the javelin, be aware of your surroundings. It fires straight forward, and then launches a rocket skyward that homes in on its target. Because of how it first fires, it is easy to blow yourself up if facing a wall or standing under a roof.

It destroys its target in one shot.

Iron sight
Weapons that use iron sights provide minimal accuracy, the least amount of magnification, but the quickest way to aim and fire. To use the various types of iron sights, line the target up with the space in the notch in the sight (all pistols), or aim the vertical metal bar to line up with the target (other weapons; if you can't see the target, you're aiming straight at them).

This type of sight is the hardest to achieve headshots.

ACOG
The ACOG scope is an actual scope. It provides a small amount of magnification and a fixed cross hair that does not diminish.

Laser
The laser sight provides the holographic sight's squarish mount, a laser in the middle, but no guarantee that the sight will remain clear. Aim the dot at the enemy.

Riot Shield
A shield that is mostly used to protect the soldier from gunfire. Very effective in heavy fire. The Riot Shield can also protect from explosions that occur in front of you. Enemies are most dangerous when in melee range.

It cannot break, regardless of how many cracks appear.

You can only use melee attacks and grenades while holding the Riot Shield. When throwing grenades or throwing back a grenade, you will move the shield and leave yourself vulnerable to attacks from the front for a short time.
