Sailors. I think they ought to make this entire mission the Navy’s job.
The ONLY change being made here is the medium you’re patrolling.
Even Star Trek extended the naval tradition metaphor. Using a type of bosun’s pipe, retaining the naval officer’s ranks, and even some of the rates (Yeoman).
Space and the Sea are frontiers. It’s a frontier force. The Navy’s already doing the mission.
Sailors and Marines.
