Orders for the assault were sent out that evening, giving the Commanders eighteen hours until they were set to depart.
Stalwart Special Tactics Unit wasn't part of the main assault force, they had been assigned to depart early and infiltrate a number of buildings on the edges of the Narsian's highly defended base in the downtown area. Some were to be cleared for infantry positions, some were to be collapsed to serve as cover for the advancing Mecha forces and some were suspected to have valuable government information in them that Central Command didn't want to lose forever.
Each of the locations was marked on their Mecha's internal map with a little red flag sporting a yellow smiley face. This was Nico's doing, of course, only she would associate smiley faces with military targets, but the other squad leaders liked them since they could adjust the emoji on the flag to represent the current status of the facility.
