Tributes

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.
Master Sergeant Harmon gave the Ohio Air National Guard 22 years.
Thank you for your service to the Springfield community. Thank you for your service before it. Gone but never to be forgotten.
Rest easy, brother.
