Does anyone have more specific burial information for Joseph?

"More About Joseph Benjamin Corbin:
Burial: Military Cemetery, Pine Bluff, Jefferson County, Arkansas (Source: Diane Nicholson Smith Posting, Ancestry.com.)"

I don't see a Military Cemetery, named as such, in Jefferson County, AR. In fact, I can hardly find ANY Corbins on Find-A-Grave in Arkansas, Missouri or Ohio (at least not in the counties named here).
