Warning! Spoilers ahead for Halo episode 1.
Paramount's new Halo series puts Master Chief and the UNSC in a complex position right from the beginning with Article 72, a new protocol serving as a dark change from the videogame source material. While John-117 and the UNSC may be humanity's best chance at fighting the alien forces of the Covenant, that doesn't mean their flawless heroes. Mankind's expansion into the stars has seemingly necessitated dark measures. The new Article 72 looks to be a large part of that, resulting in the execution order of a colony's sole survivor given to Master Chief himself.
In the first episode of Paramount's Halo starring Pablo Schreiber as John-117, a.k.a. Master Chief, he and the SPARTAN unit known as Silver Team intercept a Covenant attack on the planet Madrigal. While Halo's Covenant Elite forces are terminated, only one survivor remains: Kwan Ha, the daughter of an insurrectionist leader. Following their investigation of a nearby Covenant dig site and recovery of a mysterious artifact, Master Chief is ordered to bring Kwan back to the United Nations Space Command on the planet Reach. En route, the UNSC's Miranda Keyes speaks with Kwan to see if she'd be willing to publically speak to the other colonies about the UNSC trying to help humanity and protect them from the Covenant, who are a very real threat. However, looking to fulfill her father's mission, Kwan threatens to lie and place the blame of the colonists' deaths on the UNSC itself if they don't grant her world independence from the UNSC.
As Miranda soon learns from her own father Captain Jacob Keyes, the top brass is unwilling to meet Kwan's demands, choosing instead to enact the new Article 72, a dark new concept for the Halo show that hasn't been featured in the pre-existing canon of the games, novels, or other tie-in materials. While the exact details are not divulged in the premiere episode, Article 72 apparently empowers the UNSC to take drastic measures in the name of protecting humanity, in this case ordering John-117 to kill Kwan while claiming she died from her wounds on Madrigal (which also protects the UNSC's interests). As such, the new Halo series wastes no time showcasing the flaws of the UNSC and the immense power it wields over the rest of the galaxy, existing as a domineering military government flexing unilateral authority.
While Miranda Keyes voices her objections to the Article 72 decision with her father, John-117 takes things further after receiving the termination orders. While he likely would have carried out the execution under normal circumstances being a super-soldier bred to obey orders without question, his contact with the artifact results in the restoration of fragmented memories the UNSC had erased. As such, Master Chief chooses to spare Kwan Ha before going rogue, to the shock of UNSC High Command. That being said, it's likely that this isn't the first time the SPARTAN soldier received orders in accordance with Article 72.
While it may be a new protocol featured in the Halo series' "Silver Timeline" continuity, Article 72 does fit with what's known about the UNSC in the previous canon. Despite insurrections and resistance movements, the UNSC was the dominant power as mankind expanded into the stars. Although the military organization supposedly works for the United Earth Government, they quickly gained greater power as they became an armed interplanetary government in their own right. The UNSC may be the best defense against the Covenant, but they're still quite flawed with plenty of dark secrets. Even though Master Chief doesn't go through with it, the new Article 72 is a perfect example of that darkness in Halo's first episode.
