I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Border Patrol Agent McDonough gave the United States Department of Homeland Security 19 years.
Thank you for your service. Gone but never to be forgotten.
Rest easy, brother.
