Lieutenant Frank Pillitar
From threeA Wiki
Lieutenant Frank Pillitar is the Terran narrator of the story in WWR Illustrated Number Two that provides us information on Gēbì de Plume. In this prose, he and his Unit are being attacked primarily by mortars sent from enemy Bob robots on the other side of a ridge in the Gobi basin. After the mortars stop falling, he and his CO witness the destructive aftermath and see Gēbì de Plume on top of a fallen Martian Bertie.
There is evidence in the subject on this story that indicate that N.O.M. has intercepted the letter and possibly killed Lieutenant Frank Pillitar in doing so.
