My husband knows a gentleman who was disabled while in the military and who has been on disability status for many years. This gentleman abruptly received a notice saying that he had been "rehabilitated" and ordering him to report for a two-year training program.
The training program is in basic bookkeeping and accounting. The gentleman is over 70 years old. A few months before the training program will end he will turn 72 and thus be qualified to retire from the military with full benefits, which he could not do while on disability status.
Obviously the military is aware of their desperate shortage of people who can count.
