Headscratchers / Black Crayons

• How does Ironhide still have both his cannons if he was forced to detach them in order to escape the military bombing of the Decepticon forces during Operation: Firestorm in Revenge of the Fallen?^note This series does take place following the events of said movie, after all. Wouldn't they be reduced to little more than scrap metal?
  • Wouldn't it be possible that they were just repaired (or replaced) in between Revenge of the Fallen and this series?
