Giannis and Thanasis Antetokounmpo of the Milwaukee Bucks and Westchester Knicks, respectively, are both working hard on their basketball careers, but in the meantime, duty calls.

According to Naftemporiki, the Antetokounmpo brothers started their mandatory Greek military service on Wednesday. The two hoopsters will do work at an armor training center and have three-month terms ahead of them, the standard for any Greek citizen who permanently lives overseas.
