I’ve listened to many emotional mothers and wives over the years. I had a wife call me crying because I was “making” her husband deploy with the ship. I had a mother call me crying over the punishment awarded her perfect angel of a son (he deserved it). These things come with the job.
We don’t know enough details about Walz to come to any conclusions. Retirement process typically starts about a year prior. I expedited mine so I could start my civilian job and it still took six months. No one can retire immediately. People retire or transfer before deployments. It’s the reality of military life.
