The Sixth Regiment of Marines had come to pin the Fifth in France. Major Hughes's battalion had landed at St. Nazaire in September. Colonel Catlin followed with his headquarters company in October, going on to take charge of the provost work at Bordeaux. Major Sibley's battalion went over in November and Major Holcomb's in February, completing the Sixth Regiment and, with the Fifth already there, the Marine Brigade. What was the Marine Brigade? 1. the complete Fifth and Sixth Regiments 2. Major Sibley's battalion 03. all the Marines in France 4. the headquarters company

In a simplified way, we can say that a brigade is a unit of lower rank in the army, being photographed by all officers of lesser rank if the same army. In this way, we can say that a Marine Brigade is made up of all Marines of an army, by a group of brigades from the same army, or by a set of battalions of the same army. In this case, we can affirm that among the options given in the text above, the only one that really represents a birga is: all the Marines in France.
