Reconnaissance is the act of gathering intelligence on your enemy. It is extremely important but easily the most underestimated part of any battle-group in the SARP due to hugely over-estimated sensor technology capabilities.
Reconnaissance can be achieved in many ways but the following conditions need to be met:
Reconnaissance units are a high priority target as interest in gathering intelligence indicates you want to put troops in an area. Indicating you can quickly put down reconnaissance will either stop you from being able to plan effectively (forcing you to use search and destroy and classic probing techniques) or neglecting an area entirely (allowing your enemy to continue to hold it).
Reconnaissance units almost never engage in attacking or defense and are almost always highly modified interceptors. They can travel over very vast distances very quickly and pack extremely sophisticated sensors, communications and battle analysis capabilities. They must be extremely reliable and stealth helps.
For these reasons, weapons armor and maneuverability are sacrificed as reconnaissance is a highly specialized role. Battle-analysis equipment is used so Reconnaissance can provide useful information for further planning - estimating what enemy units are capable of so you can plan against them effectively - to recognize flaws in your own plans (and change the accordingly). You must also be able to recognize when you have been detected or when you have been fired on so you know when to bug out and return to base (once your cover is blown, the enemy will do everything in their power to distort the data you are gathering so you make sub-optimal planning decisions).
Reconnaissance units often make good surgical strike units when adapted properly as their ability to evade fire and function deep inside enemy territory for extended periods of time - though their speed, range and sensor capabilities will suffer accordingly to the loss of specialization.
There are four primary forms of reconnaissance. Although the forms each accomplish largely the same objectives, they are each utilized in different situations, depending upon the amount of intelligence already known about the enemy forces and the feasibility of obtaining more.
