I remember seeing this document among his paperwork and thinking "Oh no, was he not a citizen? Was he permanently disenfranchised?" If so, I could understand him having some animosity toward the military. This 1948 document states that the only court-martial that could affect citizenship was for "desertion in time of war."

Voting rights were up to the state I couldn't find any information about whether dishonorable discharge persons could vote in New Jersey back then, though today it appears that even felons can vote after their term is served.  

There were no limitations on the amount or kind if property he could have owned, and he could have gotten a passport or held public office (which I know became a pipe dream of his).  

But there were other consequences. There's nothing in the 1948 document about gun ownership, but according to the Gun Control Act of 1968, he should not have owned a firearm because he had "been discharged from the Armed Forces under dishonorable conditions." 

And the felony convictions in New Jersey would probably have prevented him from getting a gun, too. But I don't suspect it was a legal gun he aimed at Walt Suhaka, anyway.
