What are a First Lieutenant's Responsibilities?

A First Lieutenant is the second-lowest among Officer ranks in the USMC. This rank is held for two years until promotion to Captain.

1stLts typically have already spent a year or two in the Fleet, and probably have at least one deployment under their belt. Their fellow Marines have much higher expectations for 1stLts than for 2ndLts because of their experience. 1stLts may continue to be Platoon Commanders, or become Company Executive Officers (2nd-in-command of 80-250 Marines). Aviators most likely show up to their first Squadron as 1stLts.
