Insurgency: The Shadow (Finn the cat)

Although most of the fight force comes from loud and heavy troops, the insurgency hasn't left behind the stealth factor to with this fight. Finn before the fall of the government was a successful thief, he could steal anything without you ever finding out it was gone, but as the government fell he became more public as an Anarchist leader who stood against the new formed Communist party. He was a great danger for the  government so they captured him and locked him ,experimented on him, until his twin sister faith found his location and the insurgency rescued him. Now he serves on  the stealth ops squad of the insurgency.
