I received a daily dose of insults from classmates and teachers for accepting an ROTC scholarship in April 1972.
As an ex-Air Defense Artilleryman, I share your sentiments. I have a 22 YO son, and a 13 YO grandson, and they will not be drafted, or encouraged to enter our current military.
Given what I've read and seen over the past 15 years, the "chain of command" is hopelessly in disrepair. As a lieutenant and captain, I knew my senior leaders had my back, and they proved it on numerous occasions.
Your son was an early bloomer!

(I understand that your grandson is undoubtedly the child of a different one of your children.)
