military doesn't get charged sick days. If you're sick enough to miss work, you better be at the hospital. If the doctor puts you on quarters then you're OK to stay home but there is no charged leave for that. If you're really a mess and need to be put on long term hospitalization or convalescent leave, there is also no charged time for that. of course on the flip side, you ain't gettting much overtime pay when you get ordered to work OT or when you're put on 12 hour (or longer) shift. It all works out.
