Sometimes all you need is a crane on wheels with a funny name. A crane on wheels will probably make the process of building faster. It will probably also allow for the construction of more complex structures, like tank yards and supply depots! Yes! THIS IS HOW YOU MAKE TANKS! There are only 3 ways you can make it though: through the Light armor yard, the upgraded towed yard (any upgrade) and the tank yard itself.
Despite being very fast and potentially useful for quickly building something far away, It's high cost will make you think twice before sending it to a risky place. It is able to replace any soviet builder unless you ned some mines.
