Six of those suffering RSI are believed to be weapons-firing officers on naval ships in the Persian Gulf, the remainder bombadiers on B52 flights over Baghdad.
A spokesman for coalition commander General Tommy Franks said the incidents should remind everyone that war was never easy.
"Pushing those buttons to unleash deadly cruise missiles or drop payloads all day and night does not come without a price," he said.
General Franks said news of so many casualties had deeply affected him and he extended his sympathies to the families of those who had been hurt.
"Up until then it had been a fair fight," he said.
"We'd more or less disarmed the Iraqis 11 years ago, had been bombing their no-fly zones ever since and spent the last few months scurrying over every bit of the place disguised as weapons inspectors to see exactly where their defence systems were.
"We had a pretty good idea of what we were up against because we'd sold them a lot of their weapons in the first place."
A White House spokesperson said President George W Bush was also upset at the news of the admission to hospital of the soldier suffering a sprained wrist.
The spokesperson said the President was busy trying to write a letter to the soldier's family. It's understood to be be the letter "K".
A Pentagon spokesperson said a board of inquiry would be convened to see whether some weapons-discharge buttons were too stiff to operate effectively in prolonged war situations.
"These types of casualties could severely compromise our capabilities in any extended war, say one of more than a fortnight," the spokesperson said.
Meanwhile, in Washington, US Defence Secretary Donald Rumsfeld said there would be "hell to pay" if it was ever discovered that an Arab nation had built any of the troublesome missile firing systems.
"This must be the most flagrant breach in the history of the Geneva Convention," he said.
"As far as modern warfare goes, it had been a fair fight up to then."
