Praetor

For the faction see High Praetors.
===Overall strategy===
Praetors are the main "scholar" units of the High Praetors, and consist of an alien with very powerful abilities - they can float off the ground, have good LOS and can detect hidden units. While they are not exactly combat units, the ability of Praetors to bribe enemy units over to their side and their toughness make them very formidable units indeed.
Unfortunately, as poweverful as they are, they have one weakness - they are extremely costly. A Praetor requires not just Wealth - which the Martians simply can't create on their own - but also Knowledge as well. As a result, the Martian Horde often finds itself at the mercy of its resources, for a lot of its technologies -particularly in the late game - simply require vast amounts of Knowledge that simply can't be generated right away. Fortunately, for the Martians, they do have the benefit of better research and a faster Knowledge gather rate, but this simply cannot stop the bottlenecks caused by using Praetors instead of Scholars from impacting on the Martian Horde.
For Human factions, such as Salviatia or the Federation - the implications are clear: Martian bases must be sought out and destroyed as quicky as possible with the Conclaves (the Martian equivalent of the Universdity) being main targets for artillery or air strikes.
