Intelligence also spotting (to mark an enemy) is an important task that can lead your entire faction/team to victory.
Because of that, people need to be educated to use this function. People who are spotting should get rewards for:
Marking an enemy = points
Marked enemy which got killed = points.
Manned MG/AT Gun/AA Gun=1.25x points
Tanks=1.5x points
Planes=2x points
Only get points for successful spots not just random spotting. Say within 5m of infantry or getting the indicator for Tanks etc…
Also add a part to the tutorial for how to spot different objects.
