Topic for Force Recon.
For the noobs: Force Recon is a support that lets you call in regular Army troops to defend a position. When you deploy them, they'll move to the spot you targeted an stay there to defend it.
Recon Units are like your units but with no shield.
Force Recon 1 sends a single Fast Attack Vehicle for 3 Command Points.
The FAV is basically a Transport with a Riflemen in it, and effective against Gunships.
Level 2 sends a single FAV and 2 Tank units for 4 CP.
A common strategy is to call two level 2 Force Recons at the same time to the same location for a whopping 4 tank units with 2 FAVs for 8 CP.
Level 3 simply adds another FAV compared to level 2 for 5 CP.
