Does anyone realize that ALL the ranks presented above Lieutenant are still officer ranks, and that a separate "Command" designation has never existed? There are loose correlations in the real Marine Corps officer structure, and they follow: Second Lieutenant-Captain (O1- O3, Company Grage), Major-Colonel (O4-O6, Field Grade), Brigadier General-General (O7-O10, General Grade). Besides, the multiplayer structure completely bastardizes ecen the rank structure presented in the video games and books. —This unsigned comment is made by Griever0311 (talk • contribs) .
