Deciphering my great uncle's WWII discharge papers

I understand the basics like CPL is corporal and I have googled the 297 Engr C Bn and get the 9th and 83rd but Co C not Co A for attachments.

Also, my dad says he was a medic and I see no sign on his papers to confirm this unless 'MD' is relevant.

Here's what I have:

Organization: Co A 297 Engr C Bn.
Military occupational specialty:Section Leader.
Grade: CPL,
Arm or Service: MD,
Component: AUS.
Military Qualification: Driver and Mechanic Badge.
Battles and Campaigns: Rhineland; Central Europe
Decorations and Citations: American Theatre Ribbon; EAME Ribbon w/2 Bronze Stars; Good Conduct Medal.

ETO I assume meant European Theatre, he arrived 20 Oct 44 and came back stateside 24 Oct 45.

Highest grade held: CPL (Corporal)

Reason and Authority for Separation: AR 615-365 Convn of Govt. Sec V Cir 269 WD 45

Remarks:
0Days Lost AW 107
ASR (2 Sept 45) 54
Inactive ERC 27 Nov 42 to 4 Dec 42
Lapel Button Issued.

He had 4 years of college but was only a coporal?

Any assistance will be greatly appreciated.

Thank you,
