In "All the Dead Pilots," these are the French soldiers in the Amiens estaminet who witness Sartoris' frustration about Spoomer's affair with Antoinette. Knowing no French, he imagines they are "Laughing at me about a woman. Me knowing that he was up there" in a bedroom with her, but being unable to do anything about it because of Spoomer's superior rank (519-20).
In "All the Dead Pilots," this soldier, wearing "a peasant's smock" rather than a uniform (519), drives Sartoris back to the squadron after he finds and takes Spoomer's clothes from 'Toinette's room in Amiens.
"Kit" is the nickname given by the soldiers and aviators in "All the Dead Pilots" to the "girl" Sartoris has in London (514). They derive it, derogatorily, from General Kitchener - "because she had such a mob of soldiers" (514). The narrator and Ffollansbye don't know whether Sartoris knew about her reputation, but they bear witness to Sartoris' rage and grief after she "goes off" with Spoomer (514).
Sartoris drunkenly tries to work off his resentment toward Spoomer in "All the Dead Pilots" by making this corporal - "who was an ex-professional boxer" - wear a captain's uniform and pretend to be "Cap'm Spoomer" while fighting him with his fists (514).
In Sartoris' memory of his training as an aviator in "All the Dead Pilots," this man, who seems like a figure in a tall tale, was injured when "a cadet crashed on top of him" during flying practice in Canada (526).
In defense of his drunken strafing of troops at the front in "All the Dead Pilots," Sartoris reminds himself of this Canadian cadet aviator, who crashed his plane on a farmer during training (526).
This soldier with a "raised moustached face" in "All the Dead Pilots" (524) is "drinking from a bottle in a doorway" of the estaminet when Sartoris arrives there in search of Spoomer (522). Sartoris has to fight him in order to leave the place.
In "All the Dead Pilots," these soldiers - "the enlisted element of the whole sector of French and British troops" - are fascinated with the rivalry between Sartoris and Spoomer, two officers who find 'Toinette in a bar "where officers did not go" (516). They discuss it frequently and even make bets it.
In "All the Dead Pilots" this "Anzac major" sends the drunk ambulance driver back to his unit (527). (Anzac, sometimes written ANZAC, stands for 'Australian and New Zealand Army," to which many of the Allied troops fighting around Amiens belonged.)
After Sartoris' trick in "All the Dead Pilots," "the brigadier and the Wing Commander" arrive at the squadron's aerodrome to investigate (527). Historically, Wing Commanders were in charge of multiple squadroons. That the high command would personally see to the Sartoris-Spoomer rivalry speaks to the influence of Spoomer's uncle, himself a brigadier general in a different branch of the British military.
