[Panzergranate]

World's fastest tank.... Soviet BT-5 @ 69 MPH.

World's heaviest tank.... German Maus Tank @ 183 Tonnes (Only 7 built with one in a museum in Russia.)

Most turrets on a tank.... 5 on the Soviet T-35 "Landbattleship" of which only 63 were built and around 40 ended up captured and in use as truck convoy ecorts by the Germans. Built to look good on May Day parades in Moscow, useless in battle.

Most powerful anti-tank weapon.... 88mm. L98 FlaK 18. Six of these guns were responsible for the destruction of the entire US attack down the Kasserine pass in 1943. It can fire a AA shell 6 miles straight up.

First guided AT missile..... The wire guided "Red Riding Hood" (Germany 1945) which delivered the standard 150mm. artillery Hl/C "Holladung" hollow charge warhead.

I was a gunnery ballistics researcher at the Bovington Tank Museum back in the 1980's and a tank gunner (Scimitars) when I was in the Army.

The early Sherman tanks used aviation spirit for fuel due to the Wright Wirewind aircraft engine that powered them. Later Shermans, such as the Forefly, used Cadilac Diesel engines.

The 17 Pdr. is more powerfull than the shortened 88mm. L54 on the Tiger I.
