The Air and Coastal Defense Command or ACDC (Thai: หน่วยบัญชาการต่อสู้อากาศยานและรักษาฝั่ง) or shortly called in Thai as (Thai: สอ.รฝ.) is the Anti-aircraft warfare and Coastal defence force of the Royal Thai Navy. This Command is composed of the two Air Defence Regiment and one Coastal Defence Regiment.[3] Even though they are artillerymen, but they are trained in skills related to self-defense on the battlefield if the fire base is attacked or attacked while moving. However, they are trained protecting equipment, facilities and operations from threats or hazards in order to preserve operational effectiveness.
History
In 1975 the Ministry of Defense approved the principle of air defense[1] with the Royal Thai Navy establishing Air defense fighting unit doing Air defense duties in the area of responsibility of the Navy, such as naval bases and important military locations. On 23 November 1981, the Navy upgraded the air defense unit to the Department of Air and Coastal Defence go directly to Sattahip Naval Base using the area that has been returned from the Royal Thai Air Force. Department of Air and Coastal Defence has been greatly expanded in 1992, following the government's decision in 1988 to charge the Royal Thai Navy with the responsibility of defending the entire eastern seaboard and Southern Seaboard Development Project.[1][2] As a result of the 1988 government resolution, the responsibility of the navy has been expanded. Beyond the strength of the department, therefore, on 13 August 1990 the Navy upgraded the Department of Air and Coastal Defence to The Air and Coastal Defense Command.
Coastal Defence Command was formed in 1992 under the control of the Royal Fleet Headquarters, with one coastal defence regiment and one air defence regiment. Personnel were initially drawn from the Royal Thai Marine Corps, but are now being recruited directly. The First Coastal Defence Regiment is based near the Marine Corps facility at Sattahip. The First Air Defence Regiment was near the Naval Air Wing at Utapao. Coastal Defence Command was greatly expanded in 1992, following the government's decision in 1988 to charge the RTN with the responsibility of defending the entire eastern seaboard and Southern Seaboard Development Project. The Second Air Defence Regiment, based at Songkhla, was then formed the following year. Some analysts believe that this element will eventually grow to a strength of up to 15,000 personnel.[2]
