The two-day evolution was part of the Enhanced Mojave Viper training exercise, which enabled the Battalion to improve its capabilities as the ground combat element of a Marine Air-Ground Task Force. The exercise was the final pre-deployment training event before deploying to Afghanistan Helmand province to support Operation Enduring Freedom. (DoD photo by Cpl.
