Radar is the kind of building you want built ASAP, but after a while, I've noticed a few quirks of the system which could be improved. Firstly, Landmines show up on radar. This makes mines almost completely useless, because if you see a radar dot in a seen location it's certainly a mine. Mines should be stealthy, maybe make them visible to advanced radar, with advanced fab/combat fab being able to make completely unscannable advanced mines. Secondly, a Radar only shows a dot, even when the player knows for certain what thing is there. If an enemy unit/building drops back into the fog of war, radar should automatically extrapolate, and keep the right icon on the detected unit. Only revert to the dots if the unit is mobile, and it leaves the radar range, either by moving or by the radar shutting off from lack of power. Building identification could be permanent, because buildings don't move. This would be useful in many ways, such as, when a scout finds a base and dies, you have a clearer snapshot of what kind of army they've built if you look at it right now, and you don't need to use the chronocam to do so. It would also make minelaying a viable strategy, eg. doing a short raid, then retreating through a minefield if you seem to be taking heavy losses. As it is now, turrets work better for retreat support, when they ideally should be best for defending against raiding parties and as a last line of commander defense.
