Could being able to see and respond to an attack affect a naval crew's trauma in different ways?
Short answerYes. A sense of control could reduce one pressure, while the loss of friends in an exposed gun crew created another.
NotesBeing able to see an attacker and fire back could give a gun crew a sense of control that sailors below decks lacked. That comparison concerns one possible source of trauma. An exposed gun position could also lose most of its crew in a single action, leaving survivors with the trauma of losing their friends. These different pressures qualify any simple claim that greater visibility or participation made one shipboard job psychologically safer.
