The Python Mk II is a somewhat larger version of the original Python with a new, more powerful engine and upgraded, reactive armor. The Python was originally designed as a reconnaissance vehicle with quick mobility and a good arms package enabling it to protect itself for extended periods of time.
The Mk II came about due to the increase in enemy unit strength. The Mk II has been outfitted with reactive armor and automated defense systems along with a high velocity impact 50 caliber machine gun, 40mm grenade launcher and Charon rocket pods. The Python in addition to a traditional turbine engine is outfitted with electric hub motors to enable it to move stealthily when required to do so.

Like many of the modern vehicles today, the Python has to ability to operate autonomously and stake out areas on patrol for extended periods of time. Picture here it is entering hour 217 of this particular operation.
