Context paragraphs:
Tiger I: The Tiger I    was a German heavy tank of World War II deployed from 1942 in Africa and Europe usually in independent heavy tank battalions.  Its final designation was "Panzerkampfwagen VI Tiger Ausf.  E" often shortened to "Tiger".  The Tiger I gave the Wehrmacht its first armoured fighting vehicle that mounted the 8.8 cm KwK 36 gun (not to be confused with the 8.8 cm Flak 36).  1,347 were built between August 1942 and August 1944.  After August 1944, production of the Tiger I was phased out in favour of the Tiger II.

M103 (heavy tank): The M103 Heavy Tank (officially designated 120mm Gun Combat Tank M103) served in the United States Army and the United States Marine Corps during the Cold War.  The last M103s were withdrawn from service in 1974.  The M103 was the last heavy tank to be used by the US military as the concept of the Main Battle Tank evolved, making heavy tanks obsolete.

VK 36.01 (H): The VK 36.01 (H) was an experimental German heavy tank during World War II.  The VK 36.01 H was further development of the VK 30.01 H experimental medium tank.  There were only 8 chassies and one of the tanks built, the chassies and tank were built by Henschel.  At the time Henschel was assigned with developing a break through weapon that would help defeat the Soviets.  Also other experimental heavy tanks and super-heavy tank were built, designed, and tested in Henschel.  The development of the V.K. 36.01 H lead to the development of the Tiger I tank, a tank that played an important role in World War II.  The tanks development lead to other tank development also.  Then in 1942 the project was stopped in favor of the VK 45.01.

German heavy tank battalion: German heavy tank battalions (German: "schwere Panzerabteilungen" ), were elite battalion-sized World War II tank units, equipped with Tiger I, and later Tiger II, heavy tanks.  Originally intended to fight on the offensive during breakthrough operations, the German late-war realities required them to be used in a defensive posture by providing heavy fire support and counter-attacking enemy armored breakthroughs, often organised into "ad hoc" Kampfgruppen.

Type 89 I-Go: The Type 89 medium tank I-Go (八九式中戦車　イ号 , Hachikyū-shiki chū-sensha I-gō ) was a medium tank used by the Imperial Japanese Army from 1932 to 1942 in combat operations of the Second Sino-Japanese War, at Khalkhin Gol against the Soviet Union, and in the Second World War.  The Type 89B model was the world's first mass-produced diesel engine tank.  The tank was armed with a short-barrel 57 mm cannon for knocking out pillboxes and masonry fortifications, and proved effective in campaigns in Manchuria and China, as the Chinese National Revolutionary Army had only three tank battalions to oppose them, which consisted primarily of Vickers export models, German Panzer Is, and Italian CV33 tankettes.  The Type 89 was a 1920s design medium tank, built to support the infantry, and thus lacked the armor or armament of 1940s generation Allied armor; and was regarded as obsolete by the time of the 1939 battles of Khalkhin Gol, against the Soviet Union.  The code designation "I-Go" comes from the "katakana" letter [イ] for “first” and the "kanji" [号] for "number".  The designation is also transliterated Chi-Ro and sometimes "Yi-Go".

Tiger II: Tiger II is the common name of a German heavy tank of the Second World War.  The final official German designation was Panzerkampfwagen" Tiger "Ausf".  B, often shortened to Tiger B.  The ordnance inventory designation was "Sd.Kfz."  182.  It is also known under the informal name Königstiger" (the German name for the Bengal tiger), often translated literally as Royal Tiger, or somewhat incorrectly as King Tiger by Allied soldiers, especially by American forces.

503rd Heavy Panzer Battalion: The 503rd Heavy Panzer Battalion (abbreviated "s.Pz.Abt.  503") was a German heavy Panzer "Abteilung" (a battalion-sized unit) equipped with Tiger I tanks and Panzer IIIs.  In 1944, it was re-equipped with the new Tiger II.  The battalion saw action on the Eastern and Western Fronts during World War II.  As with other German Heavy Panzer Detachments, it was normally not assigned to a single corps, but shuffled around according to war circumstances.  Later the battalion became part of the newly formed Panzer Corps Feldherrnhalle as the Feldherrnhalle Heavy Tank Battalion.

509th Heavy Panzer Battalion: The 509th Heavy Panzer Battalion (abbreviated "s.Pz.Abt.  509") was a German heavy panzer abteilung equipped with Tiger I and later Tiger II "Königstiger" tanks.  The 509th saw action on the Eastern Front during the Second World War.  As with other German heavy tank battalions, it was never assigned to a single corps; but shuffled around as needed.

T110: The T110 Tank was a cancelled heavy tank project from the 1950s, which was due to replace the M103 heavy tank.  Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps, none of which actually met the restrictions.  but did not enter service due to the redundancy of another Heavy tank.  It was intended to be built by Chrysler, but no vehicles were ever manufactured.

Jagdpanther: The Jagdpanther (German: "hunting panther"), SdKfz 173, was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank.  It entered service in 1944 during the later stages of the war on the Eastern and Western Fronts.  The "Jagdpanther" combined the 8.8 cm KwK 43 cannon of the Tiger II and the armor and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage of spare parts and poor crew readiness.
