a witness can play chess! chess does not involve a gun or taking another humans life. and that is why a witness will not be in the military. but that does not mean we do not love our country and the freedom it and those who sadly but bravely die for it! and my grandfather was a witness and went into the army during wwII but he never really went back to kingdom hall after that not because he was shunned but because war tends to change a person!
