V2 rocket launcher

The FROG-7 erector launcher was a mobile missile launcher, used by the Soviets to launch V2 high explosive rockets at great distances.

Background
Its V-2 rocket is the first ballistic misslie used in military conflict, though it has a much older history than the Great World War II. Originally, the rocket was developed in Germany by Wernher von Braun in the 1940s as after the first world war germany was no longer allowed to use massive rail road based cannons such as the Paris gun, thus this along with a more primitive weapon called the V-1 flying bomb were born. However, due to the lack of immediate necessity for such a weapon, the Vergeltungswaffe-2 nor the V-1 was never used by Germany. The Soviet Union learned of the missile, acquired the weapon, and refined it for effective use in the Soviet military. However the Soviet union were not interested in the Subsonic V-1 and thus it faded into obscurity.

The design had many drawbacks, the process of rearming the launcher was long and tedious and often extremely hazardous to the crew manning it. However, most Soviet commanders deemed these risks necessary and used these launchers to great effect against the Allies, wreaking havoc and destruction against their bases. While technically possessing the range to fire at london from france, which is several dozens of kilometers of distance, the technology to accurately target something from such distance did not exist, and such absurd range was also far from needed.

In-game
It was very lightly armoured, with its erector systems exposed and the rocket completely unshielded, making it unsuitable for direct firefights. However, when used in a combat support role, the launcher was surprisingly effective at eliminating tanks and infantry and could be used to eliminate base defences from safe distances.
