Ironhide is the Autobots' resident weapons specialist and Optimus Prime's old friend. He is old because he is hard. He's probably had enough replacement parts to build a small army, but Ironhide doggedly refuses to roll over and die for anyone. He'll fight to the bitter end and take down more than his fair share of Decepticons in the process.
Ironhide doesn't always see optic to optic with Prime, despite their friendship. He's perhaps the more practical of the two, and more a little trigger happy, so he can be more willing to push the Autobot code to the limit if he thinks it will get the job done faster.
He has more weapons than a smaller third-world country, and he may or may not have blown up a planet with said weapons. His various weapons systems range from machine guns to gatling missile launchers. He has also gave other autobots weapon systems. He uses some human guns,but they`re nothing compared to the autobot ones.
