Tesla coil

Description
The primary defensive structure of the Allies was the Tesla coil.

History
The Tesla coil was designed by Nikola Tesla. Nikola Tesla was at first a assistant of Einstein, and helped him with the Chronosphere. However, he soon found himself in Russia, where he invented the Tesla coil. Due to the great power and range of the coil, it became a common feature at most Soviet bases, including the one holding professor Albert Einstein at a Russian facility.

Description
The structure was shaped like a christmas tree with a Van de Graff generator ball at the top. Electrical shocks would travel up the christmas tree structure and energized the van de graff generator, which launched powerful bolts of electricity a considerable distance, potentially delivering 3 bolts of electricity with a single charge-up, depending on the number of enemies who were present in the area - obviously, additional charges would not be used on already destroyed enemies.

Power
The tesla coil needed much power as it used a massive charge of directed static electricity to vaporize its enemies. This meant that the Van de graff generator had to be kept reasonably charged. It required as much as an advanced power plant per tesla coil to be operational.

The Great World War III
During the intirim, Soviet Engineers managed to increase the power, allowing it to deal with the heavier allied tanks, and installed a novel feature. Tesla troopers who fired upon a Tesla coil would not damage it - instead, they would power it up, supercharging it under regular conditions and keeping it powered under low-power conditions. A supercharged tesla coil had even greater range and power than a regular Tesla coil.
