As in the previous post, this is from a newspaper held in the Bureau of Medicine and Surgery's archives, here in Falls Church. The run is being digitized and put online in the Medical Heritage Library.
Possibly he worked for the American Forces Press Service because the newspaper used other material from them (update: I have found a piece of artwork clearly marked AFPS). These are from the US Naval Hospital Memphis' newspaper The Hospital Clipper, December 1971.
To me, he looks like he could have worked in comic strips or books. A later example, not scanned yet, is very reminiscent of Will Eisner.
Does anyone know who this is, or anything about him?
In the comments, Unknown says "That small mark after the CHAD sig reminds me of Chad Grothkopf, though I would have no idea what his later "human" art looked like."
Thank you! I believe you are correct. If you look at his Lambiek page at https://www.lambiek.net/artists/g/grothkopf_chad.htm you can see the signature mark clearly. In 1971, he would have been 57, but neither Lambiek nor Jerry Bails' Who's Who lists work for him at this time, so he could have been doing spot illos through his own company.
You can barely see his signature in this example, but the inks made me look twice to find it.

Here's two other pieces I found, both clearly showing the syndicate initials.
