The German Sturmpanzerwagen A7V Heavy Tank was Germany’s response to the first British tanks in WW1. Designing started in 1916 with the founding of the Allgemeines Kriegsdepartement Sektion 7 Verkehrswesen, which was made to start research on tanks, with the first prototype completed in late April of 1917. Shortly after, in May, the first wooden mockup was built with a rear facing cannon, which was later removed and replaced by machine guns.
The Fireflash is the first attempt the United Kingdom made at a guided air-to-air missile. Designed in 1949, it entered service in 1957 where it only remained for a year. Found on the British Swift F.7, it is the only beam-riding (SACLOS) AAM in-game, meaning it goes where your airplane's nose is pointing.
