This is a fake poster of a real poster that was used at one time to solicit soldiers into the military. Once the young men applied for service, they had to pass a physical exam. They could be turned down for many things, including flat feet.
A person volunteering for duty who had suffered a stroke and carrying a computer with closed captioned software installed to enable the soldier to understand someone speaking to them, would be ludicrous.
While Fetterman is not trying to join the military, he is applying for a job where his decisions can determine the welfare of American politics. Leaders in American politics today do not need any more unqualified and mentally disabled people in the Senate.
Uncle Sam would declare Fetterman unqualified for duty!
