Schachtellaufwark (interleaved wheel suspension) used by Tiger to both dissipate its weight across wide tracks during cross-country maneuvers, also served as defacto Schurzen (armor skirts) in protecting crew compartment from enemy rounds. Tiger had frontal Antrieb (drive) system which sprockets would gripe and rotate tracks over roadwheels and rear idlers. Model track made from soft rubber, it was painted TESTOR Flat Black and dry-brushed TESTOR Chrome enamel paint. Tank - en.wikipedia.org/wiki/Tank

Inset 1 : Tiger from German Waffen-SS unit assembled for counter-attack against Allied Normandy beachhead. Tiger tanks were assigned to independent tank battalions, hence used as Alarmheit (colloquial German for Fire Brigade) in pinching off enemy breakthroughs across Western, Eastern, and Mediterranean fronts.

Laufwerk (suspension) of large boggie wheels originally developed by 1920s-era American tank designer Walter Christie via his Christie Tank, which he advertised to possess versatile cross-country ability, high-speed hard-surfaced road travel, and light-weight airborne transportability. But massive post-WW1 US defense spending cut-backs cancelled this project.

Hence Christie sold his design to Soviet Union, which created their 1920s BT-series light fast tanks and evolved to famed 1940s T-34 medium tank design. Soviet BT tank - en.wikipedia.org/wiki/BT_tank

Rollover : Tiger side profile, Bewaffnung (main armament) was 8.8cm KwK 36 L/56 gun with range circa 4,000 yards, and two MG34 machine guns (one in turret coaxial mount, second in front glacis bow-machine gun port). Turret MG34 used for both close-in defense, but also gun trajectory-spotting for German gunners would fire a burst of machine gun to ensure gun was on target before opening fire. Real tank tracks has slackness for proper rotation and griping power, if tracks were too taunt, then excessive stress could crack track linkages. Model track slackness replicated by not gluing rubber tracks from end to end, track spacing filled in with spare hard plastic tracks at wheel bottom.

German 8.8cm gun caliber developed since WW1, but its lethal anti-tank ability was recognized in 1936-1939 Spanish Civil War (German dispatched their Condor Legion to assist Nationalist/Royalist Spaniards against the Republican/Communist regime), hence employed with great effect in various WW2 German tank and anti-tank armaments (German engineering culture prefer Centimeter usage in gun designation contrasted with American preference for Millimeter).

Tank term originated from WW1 when British introduced armored tractors as mobile artillery/troop carrier platforms to cross machine-swept No-Mans Land trench lines. Since tractor prototype was large and bulky, British concealed its identity by stating it was a special water tank transporter for frontline troops, hence term Tank was used ever since in English lexicon. Being more engineering-inclined, Germans preferred more descriptive nouns, hence used term Panzerkampfwagen (metal box fighting vehicle) or abbreviated to Panzer.
