I saw a timeline that had his unit getting called up like a year or two after he retired.
2005
He filed for office in Feb.
In March word came of a partial mobilization, nothing specific.
Walz retired in May
Warning of pending mobilization for his former unit was in mid-July.
Official notice in August
Deployment in October
Hagen, Behrends, and Herr are fos.
Walz can say he served as Command Sargeant Major. For benefits, he retired as Master Sargeant.
The weirdo Vance says using in instead of during is stolen valor
