Chief Petty Officer Andrew Hearing, port security specialist, Port Security Division, Special Missions Training Center, acts as a host nation police officer and yells in a foreign language at Petty Officer 3rd Class Billie Jo Wallaker, boatswain's mate, Integrated Support Command St. Louis, for speaking to him. Wallaker and the rest of the students attending the Maritime Security Class had to deal with similar situations throughout the course to give the instructors an idea of what the student's strengths and weaknesses were. The students were subjected to fire fights, verbal taunting, and other physical and mental stressors while attending the course.
