The top floor of these barracks on Kwajalein served as quarters for Master Technical Sergeants and Technical Sergeants, while laundry facilities were on the first floor.  Due to the hot climate, the barracks always had areas open to the weather.  Drinking water had to be distilled and was stored in canvas containers that were placed in convenient locations throughout the squadron area.
