Today's retirement ceremony for LTC Greg Wall, USA was a time to reflect on gratitude, sacrifice and most importantly the love and support of his family. Congratulations and Godspeed to this "Ohio farm boy" closing out his 20-year Army career and starting a new chapter. MMI was honored to have him as our Professor of Military Science. #usa #army #westpointgrad #longgrayline #happytrails #rotc #marionmilitaryinstitute
