To begin with, that's a great question.
This is something on which our training has evolved over the years. We make sure that they understand and learn to anticipate what exactly operational stress injuries are and what the indications are. For example, if you have a soldier within your platoon and he's starting to act differently, we talk about it, we discuss it with the leadership. If we identify something like that, then we automatically make sure that we debrief that soldier so that we can then put him into the right options, into the mental health chain of command, so we can then debrief him.
As well, we also have soldiers...they have buddies, and these buddies constantly talk to those soldiers. If they identify something that's different--if they've gone through a very stressful operation, for example--we will later debrief those soldiers so that we can then identify anything that is not natural or something that we identified. Then we can do further debriefing afterwards so that we can then point them in the right direction.
We also do enhanced debriefings once we come home as well. These are done through the whole medical chain of command so that we identify things quickly right off the bat, so that again we can make sure we're taking care of these wounded soldiers.
Just to summarize, we train and prepare ourselves to identify and then we conduct debriefings afterwards to make sure that we identify.
