The first mission is the one where the operative is mentioned to have died.

''The sole survivor of Hendricks' team was taken to the Zurich facility to undergo emergency lifesaving procedures. After being stabilized, they were quickly identified as a potential candidate for the expansion of the Cyber Ops program, and were fitted with a DNI. Prior to limb replacement surgery and full body augmentation, I personally interfaced to assist with their intergration, acclimation and training. They had potential. Unfortunately, complications arose during the procedure - They were pronounced dead shortly thereafter.''
