Chonma-ho

After the Armistice Agreement of the Korean War in 1953, North Korea found itself in need of much more modern equipment. Prior to the start of open hostilities, North Korea had acquired 379 T-34s from the Soviet Union. According to a report to the United States Congress in 2000, the North Korean military had up to 2,000 tanks garrisoned along the Korean Demilitarized Zone (DMZ) alone. Although not much is known about the North Korean military after the Korean War, it is known that they have many different types of tanks. These include the Chinese Type 59 and Type 62, as well as the Soviet T-54/55. The T-54 was probably sold to North Korea between 1960 and 1970, while the T-62 was reportedly sold in the mid-1980s. It is known that the North Koreans still make limited use of vintage World War II T-34s as well as the Soviet-era PT-76 amphibious tanks. Up to 5,400 tanks are coupled with at least 12,000 self-propelled artillery pieces and thousands of other towed artillery pieces of unknown type and quantity. Role The Ch'ŏnma has been issued to North Korea's premier armored formations, and would lead the initial attempts to break through South Korean defences. Other armour is relegated to a secondary role in this corps or to North Korea's four mechanized corps. To underscore North Korea's concept of combined arms and the importance of armour, and therefore the importance of the Ch'ŏnma, North Korea's sole armour corps is directly grouped with two mechanized corps and a single artillery corps. However, this forms the second echelon of North Korea's deployment to the DMZ, with the first echelon composed of four infantry corps, . The Ch'ŏnma is a direct copy of the T-62 with several upgrades. The Ch'ŏnma is a product of North Korea's approach of Juche, or self-reliance, which also includes several indigenous self-propelled artillery pieces. The idea of juche comes from a North Korean sentiment of abandonment by their allies, China and Soviet Union/Russia. This accounts for their drive towards overproduction and for recent North Korean nuclear developments, as well as the production of long-range missiles which provide North Korea with its longer range striking power. This all manifests itself within the 'triangle' of North Korean military development – armour, artillery and missiles. In fact, this seems reminiscent from Soviet military theory, including the application of overwhelming artillery support and the use of large amounts of armour to create a breakthrough after the initial artillery disruption. In that sense, North Korean military strategy is very mobile, and the large numbers of tanks underscores this. The Ch'ŏnma is an attempt to partially address the technology gap between its current dated tank forces and South Korean K1A1 and the US M1 Abrams tank. ==Production history==

The first Ch'ŏnma manufactured were simply license-produced T-62s with some minor differences, such as a differently shaped loader's hatch on the turret, and distinctive bolts on the front glacis. It is commonly stated that North Korea received batches of 500 T-62s from the Soviet Union, but this is incorrect. It is much more probable that the Soviet Union provided North Korea with the required knowledge to domestically produce the T-62, possibly donating a production line in the process, with series production starting in 1978. It is also often inaccurately claimed that the initial Ch'ŏnma had worse armour quality than the T-62, but this is also unfounded – no nation that operated the Ch'ŏnma complained about the armour quality, and studying of the American-captured Ch'ŏnma in Iraq in 2003 didn't reveal any armour defects either. These variants were not distinguished in North Korean service by different names, and are thus all called Ch'ŏnma. However, western sources often refer to the variant with the laser rangefinder as Ch'ŏnma-Ho II. This add-on armour appears to be similar to the Soviet 'BDD' armour present on their upgraded T-55Ms and T-62Ms. North Korea is rumored to have received a few examples of the T-72s after 1992, and possibly a single T-90S main battle tank in August 2001. However, any conclusion regarding whether the Ch'ŏnma has been upgraded to the standards of either the T-72 or the T-90S is highly speculative. Around 90% of the Ch'ŏnma-ho is indigenously produced. There is evidence, however, that North Korea has purchased entire engines, or engine components, from Slovakia. Furthermore, it is thought that ceramic components, possibly for an upgraded armour scheme, are from foreign sources, as well as fire control components, such as from Iran. It is possible that Russia is supplying North Korea with several components for North Korea's tank projects which include the Ch'ŏnma and quite possibly the Pokpung, although no hard evidence can support this claim. In August 2010 North Korean media revealed images of its new main battle tank the P'okp'ung (also known as the M-2002), which had been rumoured to have been under development since the early 1990s and to have undergone performance trials in 2002. While precise details of its capabilities remain unclear, the P'okp'ung appears to be simply a further improvement of the Ch'ŏnma. ==Deployment history==

It is unknown which units of the Korean People's Army might be outfitted with the Ch'ŏnma. It is clear that the Ch'ŏnma is a general replacement for previously employed tanks, including the T-34, T-62 and Type 59 medium tanks. It is very possible that the Ch'ŏnma will equip the spearhead and elite of North Korea's armoured forces. They are apparently deployed in sufficient numbers to be strategically significant. There might be as many as 800 T-62s in addition to the over 1000 Ch'ŏnma's in the North Korean army, of which any number could be one of the five Ch'ŏnma variants. Ethiopia purchased and used Ch'ŏnma tanks against rebels during the Ethiopian Civil War. Some Ch'ŏnma tanks were found abandoned when rebels overran the capital Addis Ababa. ==Models==

• '''Ch'ŏnma''' (also known as Ch'ŏnma-Ho I) – License-produced T-62, with minor modifications. • '''Ch'ŏnma (1986)''' – Ch'ŏnma with a rear turret bustle • '''Ch'ŏnma (1992)''' (also known as Ch'ŏnma-Ho II) – Ch'ŏnma with an external laser rangefinder above the main gun • '''Ch'ŏnma-92''' (also known as Ch'ŏnma-Ho III) – New welded turret with ERA, a thermal sleeve for the gun, a new laser rangefinder, smoke grenade launchers on the front turret, and a new engine, as well as rubber side skirts. Another minor variant of this has also been spotted, and seems to remove the turret side ERA in place of spaced armour. • '''Ch'ŏnma-98''' (also known as Ch'ŏnma-Ho IV) – Slightly larger turret of the same shape as the Ch'ŏnma-92, with improved armour, and potentially a new FCS. • '''Ch'ŏnma-214''' (also known as Ch'ŏnma-Ho V) – Adds appliqué turret armour and rubber flaps on the front hull. Variants • '''Ch'ŏnma ARV''' – Armoured recovery vehicle with a casemate superstructure. • '''Ch'ŏnma Bridgelayer''' – Ch'ŏnma with turret replaced by bridge-launching equipment. • Juche-po – Self-propelled artillery gun on a modified Ch'ŏnma chassis. The Juche-po is an improvement over the Tŏkch'ŏn artillery piece, which was mounted on an ATS-59 chassis. There are at least four M1991 versions of the Juche-po, each mounting a different gun: the D-30 122 mm, D-74 122 mm, the M-46 130 mm and the SM-4-1 130 mm howitzer. These artillery pieces can be identified by their six road wheels, as compared to the Tok-Ch'ŏn's five, and a prominent recoil cylinder which protrudes from the turret. Another major difference is that the Juche-Po has a fully encased rounded turret, as opposed to the older open-topped self-propelled artillery pieces used previously. ==Operators==
