It's one of those occupations where if in fact you're in combat arms--it all depends, but mainly it's in combat arms--your job is training. That's your job: training, training others, and being prepared to deploy when you're ready to go. That is basically how the team goes.
There are--I'll take that exactly--stressors on families, just as there are in the oil patch in Alberta, where guys have to go work up in the oil fields and so on.
So it happens to be an occupation that puts stress on families and family support networks.
