The icon of the SAM unit.

SAM is a military unit used to destroy Spores.

SAM stands for Surface to Air Missles. Each SAM can shoot two missles before needing to be recharged. Each SAM cost 20 energy packets.

In the campaign, the SAM nano schematics are picked up on the planet Octan.

In a small area, and if the spores are weak enough, then it's actually more efficient to use blasters to defend against spores.
