The Mercury Strike is a support power available for the United States through the Mercury Network Uplink. It, as its name suggests, fires a laser beam from one of the Mercury satellites in space that is particularly effective against infantry and light vehicles, though less so against heavier targets.
An interesting matter to note is that Athena Cannons benefit from the Mercury Strike; if one is used near them, the Athena Cannons can perform stronger attacks for a period of time as the Mercury Strike requires the Mercury satellite to recalibrate its position, allowing the Athena Cannons to communicate with it faster.
AI's Mercury Strike always targets the player's largest group of units, while ignoring invisible units. In addition, AI units affected by this support power will immediately target the Mercury Network Uplink.
