Meeting Amanda Waller
Relatively shortly after Superman's death, Admiral Olsen and Dexter Tolliver meet with ARGUS Director Amanda Waller, to discuss her Task Force X proposition. Waller proceeds to gives them a detailed description of all of her unwilling candidates - Harley Quinn, Deadshot, Killer Croc, Captain Boomerang, El Diablo, Rick Flag, and the Enchantress. Ultimately, however, Olsen objects to the proposition, appalled at the idea of Waller entrusting homeland security to "witches, gang-bangers, crocodiles, and the Joker's girlfriend." Waller, however, remains adamant, and intends to present her idea at the Pentagon, and Dexter is more supportive of her idea.
As Task Force X struggled to eliminate the Enchantress, Olsen and Tolliver filed into the White House, now aware of the depth of the growing crisis. As the Enchantress' power became more and more present to those on the ground, Olsen was made aware of how a classified satellite and several secret military installations had just been destroyed, falling under either the power of the recently defeated Incubus or the Enchantress. Olsen wondered how the Enchantress even knew of those locations with Tolliver unable to give a satisfactory answer. Minutes later, they watched the Enchantress' magic destroy an aircraft carrier, and one of them suggested that they use a nuke to destroy her, which was met with agreement, but also confusion as to how such a task could even be carried. 
Admiral Olsen, as a member of the US Armed Forces, is quite patriotically dedicated to his job and country, with a great deal of posthumous respect and admiration for Superman, whom he views as a national hero, with Olsen even reprimanding Amanda Waller for looking cheerful in light of Superman's recent death. He doesn't care for Waller's amoral methods, however, since he, unlike his associate Dexter Tolliver, expresses dismay as her Task Force X proposition.
