 Soldiers from the Second Combat Aviation Brigade traveled to Rock Naval Base Po-Hong to conduct survivability operations using the Phase 3 Modular Egress Trainer, or as it's commonly called, Dunker Training. For first-time trainee Army Private First Class Kayla Brinkerhoff, fear was the first thing to set in. I'm not afraid of water normally, and to be clipped in like that was a totally different experience for me. It's definitely a mind over matter thing, you have to try not to panic, and at the first time I did panic, you know, it's just like, oh, get me out of here. Very different than what I initially thought, actually, so it's a lot more mental than it is anything else. Although he trains in a controlled environment, Chief Instructor Kwak Tong Hyun realizes the real-world implications of his instruction. I heard that one of the soldiers was sorry for me, he was a real accident, he was a survive. So I heard that, it really made me crying. That much I feel, it's a great job I'm working for this one.
