"Guardian" walking machine

The "Guardian" walking machine is probably the first heavy machinery that will be available to you, as it is more common in rewards than any other other heavy machinery in the game (although still fairly rare). It can be produced at the tank factory once the appropriate technology is researched, but as that technology is a Level 10 mechanics research, it will not be available for a while.

The Guardian is equipped with two cannons which fire at a decent rate. They also do explosive damage, making this an effective unit against groups of enemy troops.
