"What is going on on Anaxes that is so important that Rex and a bunch of clone commandos must go there?"

Maybe clone intelligence got word that a terrorist attack will take place at a major [insert public place here, like spaceport, government building, mall, etc.] by Separatist commandos, and clones are sent in to prevent it from happening—but they arrive to late and the attack is in progress. They have to kill the insurgents and try to protect the civilians. A kind of test of skill for the Bad Batch.
