The other vacationers were a bit noisy...
To meet needs in Iraq, Afghanistan, and elsewhere, a number of National Guard and Reserve troops have been called up and pressed into active duty. Despite a 1994 law designed to give Guard and Reserve troops their old jobs back, or provide them with equivalent positions, some troops have run into problems when returning home.

Larry Margasak of AP cites one example (emphasis mine):

Reservists and guardsmen who returned to the Prince George's County government outside Washington, D.C., were among those who fell into a gray area.

The county required that they exhaust their leave before receiving a county salary supplement that bridged the gap between military and civilian pay. This meant some employees had to count some of their time in a war zone as vacation days or forfeit the extra pay.
