Major Story Arcs
Soldier and SHIELD
Dugan participates in numerous missions as a member of the Howling Commandos. He remains with the US Army until sometime before the breakout of the Korean War. Partway through that conflict he is drawn back in, and works with Fury as part of the reformed Howling Commandos through both Korea and Vietnam. During this time he starts to become involved in SHIELD, and he is eventually placed in charge of security for the SHIELD Helicarrier. He is also given command of the Godzilla Squad, a group specifically created to hunt and contain the Godzilla monster; during their numerous confrontations, he comes to bear a grudging respect for the monster. He is elevated to Deputy Director, and briefly placed in charge of SHIELD following Fury's death. When his death is revealed to be a ruse, Dugan gladly gives up his new position.
Nick Fury vs SHIELD
Dugan is apparently killed in what is later revealed to be an effort by the mysterious controlling council to instigate a survival of the fitness amongst the leaders of SHIELD and HYDRA. Dugan is briefly replaced by a Life Model Decoy during this time. He later resigns from SHIELD, but his resignation is short-lived. Shortly after Fury recreates SHIELD, Dugan rejoins the organization. When Nick Fury leaves for a time, Dugan operates as second-in-command to Maria Hill, and is the head of mutant affairs.
Under orders from SHIELD leadership, Dugan and several of his colleagues attempt to capture Captain America. Their efforts fail, and Dugan expresses discomfort at being asked to turn against his friend, and distaste for the side that SHIELD has taken in the war. At the conclusion of the war, when SHIELD is taken over by Tony Stark, Dugan attempts to resign due to his disagreement with Stark and Stark's policies. His resignation is not accepted, and he is kept on as a leader at SHIELD and given control of a weapon capable of trapping huge areas of land in the Negative Zone. Later, despite working with Stark and for SHIELD against his will, Dugan aids Stark by convincing Hill to shut down the UN to allow Stark to pursue the Mandarin.
Dugan is ambushed and apparently killed by s Skrull who has taken the identity of Contessa Valentina Allegra de la Fontaine. He is impersonated by a Skrull, and spends the remainder of the Invasion held in stasis, and after its conclusion is rescued, alongside the other Skrull victims, by Iron Man. He is later convinced to attend a support group meeting for the victims of the Skrulls.
Fury calls on Dugan, now operating a version of the Howling Commandos as a private military company, to aid him following a difficult confrontation with The Gorgon. Dugan soon discovers the SHIELD has again fallen under the control of HYDRA. He and his group join Fury in attempting to bring down HYDRA and the Russian LEVIATHAN. These efforts whittle down his group's membership to himself and Jasper Sitwell. He and Sitwell are arrested by the UN, and later released following the conclusion of the Secret Warriors event.
