Military Law is different than Civilian law, but the president being Comander-in-chief of the US Armed forces and having the power to pardon can he can do it for a military sentence? Say Bush doing it for the Soliders that mistreated the guantanamo bay POWs
Yes.
I believe that the President’s pardon authority extends to any criminal matter arising under federal law.
According to the Justic Departmentthe POTUS can pardon military convictions.
