Among U.S. soldiers stationed in Korea on a rotational basis, small-time soldiers are prohibited from owning or driving their own vehicles.
They got into accidents while driving, and if they got into an accident, they were subject to the Sofa Agreement, so the U.S. Forces Korea Command banned them from driving their vehicles due to anti-American sentiment.
Instead, those with limited time or executives above a certain rank are allowed to own their own vehicles.
