The Desert Battle Dress Uniform (DBDU) is a U.S. arid-environment camouflage battle uniform that was used by the United States Armed Forces from the early 1980s to the early to mid 1990s, most notably during the Persian Gulf War. The Desert Battle Dress Uniform was designed in 1970 and uses a camouflage pattern known as the Six-Color Desert Pattern or colloquially as Chocolate-Chip Camouflage and Cookie Dough Camouflage. The camouflage received its nickname because it resembles chocolate-chip cookie dough.

These shorts are commonly referred to as "silkies" or "ranger panties" for their silky smooth feel and that they are commonly used as underwear in the military during long outdoor operations.
