Captain Mainwaring often a sympathetic subtext to his own personal neuroses; it is apparent several times that he devotes his energies to his Home Guard unit for a sense of comradeship and purpose lacking in other parts of his life, such as his career and marriage. On one occasion when his men spurned a parade to play darts against the ARP he expressed bewilderment, saying coming to the platoon is "the highlight of my day". It is frequently implied that he is trapped in a loveless and unhappy marriage to Elizabeth, his unseen wife, who is domineering, neurotic and withholding of affection.
Captain Mainwaring independently, although not always with the best of results. In "A Man of Action", Walmington is cut off when a bomb damages the railway and waterworks. Mainwaring imposes martial law and takes power from the Mayor. Under his law people need permits to take a bath and looters will be shot. He changes position when this power is taken from him by an official from GHQ, describing such an act and the imposition of martial law as "monstrous". Mainwaring often claims to know something, only to be proven wrong almost immediately. Men under him, however, are mostly devoted to him.
