Type 33 Energy Manipulator

The T33EM, also known as the Energy Charger, is a new weapon in 
the Sangheili Armed Forces, the Sangheili army after disbanding from the Covenant.
The weapon is known for its extremly destructive force, firing off a huge gleaming green ball of explosive energy. A small computer chip make the energy home in on heat sources, such as enemy soldiers. Unfortantly however, if the charge is shot before reaching a enemy, it will explode violently, blowing up not only its shooter, but most likely his entire squad, and the enemy at the same time.
