1 is the most serious, a misdemeanor punishable by up to six months.
2 is a disorderly persons offense, usually a class 1 misdemeanor maxing out at six months.
3 is the least serious offense, generally punishable by up to 30 days.
So a real hardass could sentence him to the max on each one to be served consecutively for a total of a year and a month. I wouldn't expect this.
More likely they give him something like the middle range for the assault charge.
I haven't double checked this shit at all and got the information from a defense firm's website. They don't list the actual statutes by number but just by name on the public case information, and I'm not paying for document access for one Arizona case.
So, could be inaccurate, subject to change.
