Individual or group?
Four agents: soldier, support, hacker, infiltrator. Randomized appearances, can be augmented but not altered in appearance. When they die, these agents are cloned and remade, so their original species is unknown. Most agents will be clones, so I put machine as species: "Clones allow replacement bodies for our Agents, a somewhat brutal but necessary act if we are to succeed. Once you've scanned a civilian, you can select them and divert a small amount of resources to obtain a deeper scan, giving you info on their DNA traits. Once you have a target, use your Hacker to hijack them and send them back for cloning."
