Recruits: Aye, sir! Narrator: The day before, recruits from the gender-integrated Hotel Company assemble in front of their barracks for a briefing. Although female recruits have trained at Parris Island since 1949, gender-integrated companies didn't emerge until 2019. As of January 2021, this group of recruits was the most gender-diverse company of enlisted recruits in the history of the Marine Corps. And among those in Hotel Company are a brother and sister from Georgia -- 21-year-old Lazaro Cisneros and his 19-year-old sister, Mayra. Lazaro: My sister and me are here doing the Crucible together. We're in the same company. We usually don't see each other often, but we always get, like, a glimpse of each other.
