According to Wikipedia, Reservists are "...drilled one weekend a month and two weeks of annual training during the year, but have done much more in times of war or national crisis....After the 11 September attacks of 2001, Reservists have been mobilized to support combat operations." So what I'm seeing is that his one weekend per month and two weeks during the year are standard part of his Reservist duty.

Correct me if I'm wrong. I'm not trying to be argumentative, just in search of the facts.
