Not true: Leave, unlike liberty, is a right. That is what the base XO is for. If you lost out, it is your own fault. As we had a fair amount of time before and after a patrol, many chose not to take leave when it was convenient for the unit. As for sick leave, when I was active, you got 30 days per year and could accrue 60 days. That may have change with the maternity leave changes.
