Equipment Operator Constructionman Ken Carter performs a buddy check on a fellow Seabee from Naval Mobile Construction Battalion (NMCB) 3 during a chemical, biological and radiological (CBR) drill to test the team's ability to react to enemy CBR attacks. NMCB 3 is conducting their final graded field training exercise (FTX), testing the battalions overall readiness through a variety of realistic scenarios encountered during routine Seabee deployments. NMCB 3 provides commanders and Navy component commanders with combat ready warfighters capable of general engineering, construction and limited combat engineering across the full range of military operations.
