Just a couple of things to think about-and no being a mom isnt always easy. But-if you are a numbers person heres something to think about-Does your son drive a car? or Ride a motorcycle? both are MUCH more dangerous than serving in the armed forces-TV commentators dont talk each night about the thousands of Americans injured in car accidents each day-and more than 50, 000 die each year in car accidents.
If you think the world is a more dangerous place than in the past-you are mistaken-but i also understand that its hard when its your child.
Lastly-something i have arrived at after having my husband deployed more than once-and loosing friends who have surivived multiple deployments in car accidents-If its your time-God is going to call you-and its not going to matter if you are in harms way-or sitting on your front porch.
I know this is not an easy thing-my husband, my brother, my brother in law and my best friends husband are all soldiers-many of my childrens friends are soldiers. Love you son, support him-and know he will be a better man for it.

to both you and the OP.
