I will venture to say one of the most difficult things a spouse must do is watch their husband/wife leave home as they are called up to duty. The heart wrenching role of being the spouse to a military man/woman is such a difficult one. These women have taken that role and made themselves active participants, working WITH their husbands. They can't physically be with their husband so they do the next best thing--show their support in a very public, loving way.
Turn up the volume and listen. Also, watch the video, these women are helping their husbands and you can see the pride in their faces for their spouses. If you can watch this, WITHOUT shedding a tear, you must be missing some emotional hard wire.
