- "Ground units, Area is clear of Heavy enemy presence."
- — Thunder to the S.F.S.G. Troops
Codename Thunder is an American who is sent to complete three tasks in the mission "Clearing Out" on Call of Duty: Modern Warfare 3: Defiance. He is a playable character that never appears outside of this level.
In "Clearing Out", Thunder is given three extremely time specific tasks that must be completed extremely quickly or else the mission will be failed. His tasks, in this order, are:
- Provide aid to the soldiers from Running For Cover (referred to as Alpha Team) by destroying a Russian Convoy.
- Provide covering fire for an ally unit that has been forced to entrench itself in an apartment building. After this is done, two enemy entrechments must be removed via The AC-130's 40MM or 105MM guns.
- Provide covering fire from multiple enemy armor and troop transports while some ground units evacuate civilians from a Nevada business sector in an unidentified town.
