Royal Marines and Royal Navy Rank Equivalents for Warrant Of

Royal Marines and Royal Navy Rank Equivalents for Warrant Officer and higher

The following are the rank equivalents between the Royal Marines and Royal Navy while at official group servers (ports, forts and the RMC training center.) Please note, while on a ship, the Captain of the ship has the highest authority, and cannot be ordered by any rank on-board it as a crew member. As well, men below the ranks of Midshipman or Sergeant Major are not to be ordering each other, or the men below them in rank. Furthermore, Regimental Commanders have no command over Admirals, nor do Admirals have command over Regimental Commanders, when rules are being being followed. (However, an admiral may order a Regimental Commander if they fail to abide by the official rules, as well as vice versa.)

Royal Marines - Royal Navy (Royal Marines rank in equivalence to Royal Navy rank)
Lieutenant- Midshipman
Captain - Acting Lieutenant
Major - Lieutenant
Lieutenant Colonel - Commander
Colonel - Captain
Brigadier of the Marines and higher - Commodore


Please note, regardless of rank, the Royal Marines and Royal Navy must work together with full cooperation. On a final note, these rank equivalents only apply when on the applicable teams, for example, a Navy LR may not use his RMC rank while on the Royal Navy team to avoid calling his naval superiors Sir or Ma'am.
