families, is still limited despite an aggressive family housing construction program. Those authorized to live off-base will receive an overseas housing allowance. There is an elementary school, named Osan American Elementary School; a middle school, named Osan Middle School as well as high school, known as Osan American High School the middle and high school are now conjoined). These schools are for command-sponsored children of military members. Contractors (even command sponsored) should be prepared to pay upwards of $25,000 a year for this privilege. Some families choose to come without command sponsorship; these family members may use the facilities (including schools) on a space available basis. If family members come, they will be able to receive the local OHA rate, whether or not the servicemember makes the list to move off base and regardless of rank. The government will not pay for their transportation to Korea, in most cases. Under normal circumstances, unaccompanied airmen live in one of the many dormitories on-base and eat in the dining facility, thereby receiving a meal deduction from their basic allowance for subsistence. Airmen receive cost of living adjustments (COLA) if living off base, and partial COLA if living in the dorms, which varies by rank, living situation, and dependents. E-5s and above may live off-base if NCO or officer dormitory space is not available; in some cases this has also been extended to higher ranking junior enlisted airmen (E-4s), depending on dormitory occupancy availability and policies in place at the time. The compact nature of Osan AB lends itself to walking and bicycling. For single and unaccompanied airmen, one of the attractions of a one-year assignment to Osan AB is the opportunity to follow their Osan tour with an assignment at the base of their choice, called a "follow-on assignment." If a position is open at the desired location, unaccompanied airmen in Korea (or other unaccompanied locations) have priority over other airmen in filling that position. This benefit is not available to those serving accompanied tours with family, or to those who extend their tours; those airmen must use the normal assignment selection process for their next assignment. There are many bars and clubs off base, mostly in the Shinjang-dong district and many base members spend much leisure time at them. If the bars do not abide by certain standards, the Osan Military Beverage Control Board may place them off limits to military
