Mexican War pension documents

I am having a difficult time crafting a citation because I don't know what to call this document that is from FamilySearch's United States Mexican War Pension Index, 1887-1926:

https://familysearch.org/ark:/61903/3:1:33SQ-GBC8-PBJ?mode=g&i=2133&wc=M61R-NM9%3A321929601%3Fcc%3D1979390&cc=1979390

I would appreciate your informing me what document it is.

Thank you.  That was what I was inclined to call it, but didn't know if it was as simple as that.
