Genre
Satire, War Poetry
Setting
The setting is the speaker's imagination, in which the major stays safely at a military base and a hotel during the war, and toddles home after the war, where he dies in bed.
Tone
Sardonic, Acerbic, Angry
Protagonist and Antagonist
The protagonists of the poem are the young soldiers who lose their lives in battle. The antagonists are the corrupt military officials who enjoy themselves while sending the soldiers to their deaths.
Major Conflict
The major conflict in the poem is that the military officials (appearing in the poem as majors) are corrupt; they do not provide a strong base of leadership, and thus the entire war effort costs countless of young men their lives.
Climax
The climax arrives when the poet bitterly describes the way the major would toddle safely home after the war and die in bed.
Foreshadowing
N/A
Understatement
The comment that the speaker (imagining himself as a major) makes about losing "heavily in this last scrap" is an example of understatement (Line 8). What is referred to as a "scrap" is likely a horrendous battle that cost many lives.
Allusions
The phrase "glum heroes" refers to the sense of patriotic disillusionment that Sassoon experienced after fighting in World War One. This contributed to his anti-war sentiment.

Hyperbole
Satire is often created using over-exaggeration. Any of the details about the major could be considered hyperbole: his puffy petulant face, the way he guzzles and gulps in the best hotel, etc.
Onomatopoeia
"Gulping" is an example of onomatopoeia.
