The story isn’t exactly clear, but it appears that they had just started field training that week.

The DA is going to try to get them to make a deal to testify against the Chauvin in exchange for reduced charges. There is no way any of these guys will get a fair trial.

The cop standing was cooperating before his,arrest.

I don't know how all departments work, but for new officers, there is an academy, then training with a Field Training Officer, and then they are out on their own for evaluation.

I'm going to guess that you on right on this. The officers are being charged so that the prosecution can threaten them with lengthy sentences. They fired the officers instead of putting them on leave, and most likely their lawyers told them to invoke their 5th Amendment rights. Now, the only way they can induce testimony is to threaten them. Again, just guessing, but had they not been fired they would have willingly cooperated in giving testimony.
