Frostrattler

The Frostrattler is a stationary gun turret, firing low-temperature shells with a small explosive charge on the tip. Because the cold freezes the material, and the explosive charge shatters it, armor is easily pierced. The Frostrattler has been proven capable of taking out large enemy vehicles, but, with a rather large amount of shots.

Primary use
The primary use of this weapon is dealing damage to those inside of the vehicles, as the shells will shoot straight trough the vehicle's armor. Vehicles can be taken down easily by shooting at the wheels, as the force of the shell will break the axis. Because the shell does not have a large explosive radius, it is generally not used to attack infantry. If the user would be able to hit the shell within 3 meter (9 feet) of the target, the target has a chance to be hit by ice shards, acting as shrapnel. A direct hit, on the other hand, is capable of piercing trough a target, and killing him or her instantly.

Deployment
The Frostrattler can be used by any soldier, but trained soldiers get priority. The weapon shall be put stationary as permanent defences, in the case of war. The weapon can also be fixed on certain vehicles, which would change the vehicle's classification. An extra CCG would be needed to operate the weapon.

Ammunition
The weapon fires frozen shells, with explosive tips. On impact, the tip explodes, and the shell penetrates the target. Ice shards, burst in random directions when the shell's tip explodes. Due to the shape of the shell, the explosion fires backwards, therefore boosting the shall even further into the target, and destroying anything behind the shell. After the shell penetrated the armor of it's target, it's tip will be flattened by the force, which will make it destroy the other side of the vehicle, due to it not being able to pierce trough the other side. It will almost "push" the other side of the target's armor out of the frame.
