Panther in Red, a transgenic warrior

Subsisting on cat-food and enemy fallen and armed only with a sword, this bio-weapon is capable of courageously suffering and dying in battle which makes it morally superior and cheaper both to purchase and maintain than the cowardly, chivalrous and despicable Drones. A must have item to ensure your army is clearly the "Good Guy" especially when up against unchristian, but admittedly heroic, suicide bombers.
