In some specialty schools in the U.S. military the students have their regular class hours and need to supplement that with extra study hours. The amount needed can vary from 10 to 35. 35 extra study hours per week is the maximum that can be mandated, so it sometimes is referred to as "Mando Commando".
It's the last week of classes before the "comp" (final exam). Everyone in our class unit is on Mando Commando hours for the week.
