Source: World War IV: the African Front
Location: The Battle of Kenya
Threat Assessment: 6. Meant to be a distraction. The new Mau Maus took 25 bull african elephants and first armor plated them. Then they gave them both the equivalent of elephant PCP and occassional painful electric shocks. Finally, on the back of each was a cannister that was releasing into the air an experimental gas weapon that gave humans fearful hallucinations. Released, or rather unleashed, just before the big battle they played havok with the the other side's troops.
Limitations: Mad and insane.
