Yes, if the military person is not suicidal himself and if the family itself does not need care and support.
Those close to suicidal individuals have other needs and have to obtain care. They cannot act as sentinels in these extremely difficult moments in their family life. They have to take care of themselves and the other members of the family and know how to support the spouse who is not doing well. We try to avoid training loved ones, especially when they are going through difficult times. Of course at other times, that is possible.
