This section is in development; I'll be adding to it as I research and find accurate information.
- Structure of a Regiment: (Updated 9/23/2004)
- 4 Marines to a Fire Team (4)
- 3 Fire Teams to a Squad (12)
- 4 Squads to a Platoon (48)
- 3 Line Platoons and 1 Weapons Platoon to a Company (192)
- 5 Companies to a Battalion (960)
- 5 Battalions to a Regiment (4800)
NOTE: Field Artillery Units are not referred to as a Company; they are called a "Battery". As an example, E Btry 2Bn 11th MAR. You will know this is a Field Artillery Unit where "E" is the "Battery" rather than a company name.
- 7th Marine Regiment:
- 3/4: 3rd Battalion, 4th Marines (a/k/a Thundering Third)
(Includes the following companies: India, Kilo, Lima, Weapons)
- 3/7: 3rd Battalion, 7th Marines
- 3/11: 3rd Battalion, 11th Marines
- 2/7: 2nd Battalion, 7th Marines
- I believe H&S (Headquarters & Supply) is part of this as well, though they may be referred to as HQ, not to be confused with an HQ Platoon though.)
