RA3 - Allies alltech1
Allied Airfield

Airfield with Heightened Clearance Upgrade, hence the two blue lights.

Heightened Clearance is an upgrade for Allied Construction Yards and Command Hubs. For 1500 credits, it grants the commander access to tier 2 technologies, allowing the commander to deploy more powerful units and construct advanced structures, as well as unlocking Max Clearance.

The clearance signal is only broadcast in a small radius around the Construction Yard or the Command Hub. Any structures outside of the broadcast radius cannot produce tier 2 units until a Construction Yard/Command Hub located nearby purchases the clearance upgrade.
