Seabees assigned to Underwater Construction Team One (UCT ONE) and Underwater Construction Team Two (UCT TWO) perform pre-dive maintenance checks prior to commencing dive operations during diver training aboard USAV Matamoros (LCU-2026). Diver training is a two-week, joint training evolution between UCT ONE and UCT TWO designed to reinforce standard operating procedures, qualify personnel, maintain proficiency and evaluate dive protocol during scuba, surface supplied and recompression chamber operations.
