The Revel marine battalion was created in the summer of 1917 as part of a program to create so-called "death units" from volunteers. These were shock units that were distinguished by high combat readiness and discipline. The command staff was recruited from among officers and non-commissioned officers who had distinguished themselves in combat. The revel battalion was a unit whose personnel were recruited primarily from the Revel base's seamen, teams that were stationed at ship repairs and training units of the fleet.
