The Code

This show could really use a military adviser.

Captain Maya Dobbins needs some advice on wearing the uniform. IE: No Marine ever wears their garrison cap and an angle. Really looked stupid.

The medical doctor was constantly referred to as Commander, while wearing the 2 full stripes on his uniform sleeve of a navy lieutenant, US Navy rank 0-3.

Two officer ranks in the US Navy can be addressed as Commander - a Lieutenant Commander, Navy rank O-4 with 2 full and one 1/2 stripe --- or a full Commander, Navy rank O-5 -- three full stripes.. An O-6 (4 full stripes) is a navy captain. The US Coast Guard used the same system as the navy.

In the Marines, along with the Army and Air Force O-3 officers are captains, O-4s are majors, O-5 are Lt Colonels, and O-6 are (full/bird) Colonels
