Just brushing up on the structure of the Royal Marines, appreciate some verification: -2 Fireteams make a Section. Each Fireteam is composed of 3 Marines and led by 1 Lance Corporal/Corporal. -A Section, is led by a Corporal and is composed of 8 men in total. -3 Sections form a Troop. A Troop is led by a Lieutenant, an experienced Sergeant and a radio operator. Troops are composed of 30 in total. -3 to 5 Troops make a Company/Squadron? A Company is commanded by a Captain, a Sergeant Major/Warrant Officer Class 2 and additional staff. -6 Companies/Squadrons make a Commando unit. A Commando unit is commanded by a Lieutenant Colonel/Colonel, a Captain and a Regimental Sergeant Major/Warrant Officer Class 1. 2 of those companies will be an HQ and Logistics company. I understand that unit sizes and ranks in charge can vary according to the role and environment they are operating but is there anything significant I am missing? I've noticed that (R) Sergeant Majors are ranks still being used, however on wikipedia, it doesnt include them? Have I got their equivalent WOs correct? Also with future commando force, is it likely that the term "squadron" will become more regularly used? Many thanks!
