The 50cal is the most common Messenger variant and is used to patrol most AN held areas. These are usually supported closely by normal transport messengers whose goal is to simply insert soldiers quickly and safely due to the messenger having thicker armor than most other transports and being more sealed up making the soldiers inside more protected.
The basic .50 caliber Messenger is only suited for attacks on small infantry platoons, as the gun is not well-suited to take on heavy armor.
The Messenger 50Cal is based on the Humvee. It is equipped with the standard .50 cal machine gun.
