The traditional arm-of-service colours appear as lapel facings and as piping on shoulder straps. Generals wear an inner piping of gold braid; other officers wear silver piping. Lapel facings and piping are maroon for general staff, green for infantry, red for artillery, pink for armour, black for engineers, yellow for communications, dark yellow for reconnaissance and various other colors for the remaining branches. Combat troops wear green (infantry), black (armour), or maroon (airborne) berets. Logistics troops and combat support troops, such as artillery or engineers, wear red berets. A gold or silver badge on the beret denotes the individual branch of service.
