Highland Rangers

The Highland Rangers are a territorial paramilitary police force. While they are independent of the Star Legion, they can and have acted under Legion command during wartime. Unlike the giant Legion ships-of-the-line, the largest Rangers vessel is the patrol corvette. They also operate schooners and HUVs, which allow individuals and small detachments of Rangers to enforce Highland law.
The rangers operate everywhere within the Highlands, but they are probably most active at its edges, where the problems and criminal activity of the Midlands leaks over into civilized space.
Rangers generally don't wear uniforms, but can be recognized by the Encircled Maltese Cross badge awarded to each Ranger at commissioning.

Individual Rangers buy their own personal gear and are paid a stipend to compensate for the cost of equipment. The unit provides heavy equipment, such as vehicles and ships.
Rangers are trained in combat, search and rescue, and hostile environment survival. They overwhelmingly come from non-urban environments, including vacuum worlds and asteroid colonies.
The Senior Captain of Rangers supervises the organization. Ranger Companies are commanded by Ranger Captains. Lieutenants (pronounced left-tenants, in the British fashion,) command detachments of Rangers. All other Rangers are considered equivalent to junior commissioned officers, since each holds a commission from Parliament. Specific ships or units of Rangers assigned a specific job will be led by a Tactical Leader. This is not a rank, but a temporary assignment, usually given to the Ranger with the most experience in performing that specific task.
The Rangers primarily operate within the borders of the Highlands working in law enforcement, search and rescue, government corruption investigations and organize crime suppression. They also act as a custom service, of sorts, though their duties in this area primarily consist of keeping Midland pirates out of the Highlands.
