Design and technical characteristics

The carrier vehicle is constructed around the chassis of 6x6 MAN KAT1 transport vehicles primarily used for military purposes. It consists of two main components and three independent sections with the crew cabin located in the center offering space for four passengers or artillery crew and a large back portion encasing the automated artillery station. The weapon is stored and remains concealed inside the carrier until the large roof hatches open in preparation for fire missions.

Protection

The vehicle is fitted with several layers of armour that provide overall protection in accordance to STANAG 4569 level 2 similar to the Didgori APCs.

Armament

The primary weapon GMM-120 is an automated weapon station equipped with a digital fire control- and navigation panel with GPS. It is further supported with a state of the art communication system. The rate of fire is 15 rounds per minute with ranges of 480 m to 7,100 m. The vehicle can carry a total of 60 and different type mortar ammunition with the module itself carrying 10 rounds while two separate containers carry 25 rounds each. The weapon has a 360 degree traverse and almost 90 degree elevation angle. During transport the weapon remains concealed and won't be operated. However it takes less than a minute to have the weapon system ready to fire or relocate.

For self-protection, the carrier is armed with a NSV heavy machine gun mounted on top of the driver cabin. This however provides the gunner only a limited traverse angle so that the vehicle ideally has to face the threat.

gollark: "Simple" would be potatOS 5rot26.
gollark: I mean, it doesn't seem like it'll actually encrypt things.
gollark: What does it *actually do*, though?
gollark: Tell whom?
gollark: Firstly, this makes no sense what are you even doing; secondly, repeating it is pointless; thirdly, this is server-heavy and should be fixed.
