What are common pleas deals for assault on public servant in Texas?

I'm dating a girl who is currently facing a FELONY charge of assault on public servant with bodily injury. It's a case of a good person doing something very stupid.

Trying to make this as succinct as possible. She had too much to drink on a girls night out and caused a scene at her apartment complex at 2 AM and someone next door called 911. A zealous female police responded to the call. The lady officer is claiming that when she showed up that my girl became upset and charged up to the officer and started fighting her. A witness has made a sworn statement that my girl never charged her but just was very upset and intoxicated but never a threat other than just yelling and cursing at the police to mind her own business. Yes, she was drunk and stupid but the witness said that she was leaving the scene when the officer ran up and pushed her into a wall and knocked to the ground when my girl had her back turned to walk back to her apartment to sleep it off. She was arrested and booked on assault to public servant with bodily injury, a 3rd degree felony in Texas.

She is quiet, sweet person who clearly had too much to drink and made a scene but now faces very serious consequences. She had no priors, works and goes to school part time and overall a good citizen. There was obviously a scuffle but feel like the officer escalated it just as the girl was about to go home anyways. I'm worried that since she is indigent and has a public defender that she will be railroaded and that she might be doing time with a 3rd degree felony charge (2 years in jail AT LEAST).

Has someone been charged with this? If so, did you take a plea bargain to avoid a trial and if so, then what the lesser charge? I understand that she needs to talk to her defense lawyer but just want to see what has happened to other people in this situation.
