- I am a retired army reservist but I spent 7 of my 21 years in a 28th division unit (Pa Army national Guard): 1st battalion 103rd armored regiment which in WW2 was the 628th TD BN. I was also at one time president of the National Guard Armor Reunion Association which was the associated organization for the 628th TD BN, 628th Tank BN, 1/103rd Armor but the NGARA doesn't exist anymore. I wanted to know more about TD as I found out my former unit was attached to the 5th Armored Division during the entire WW2. Though I am actually a Quartermaster Corps soldier I loved being in an armored unit and especially it was a TD unit at one time. Thank You and God Bless. V/R SSG Kraig Morris USAR,Ret.
