There was a bit more to it, though. He was now a Gauss technician - a sort of a combat engineer. In addition to demagnetizing the squad's rifles when they jammed and carrying the Field Projector to counteract the Exon jammers from affecting the ordnance, the duties of a technician extended to cover carrying extra shells, picking up empty cases, and be an auxilliary spotter for the squad. Techs were more often than not experienced soldiers who would have otherwise made squad leader if it weren't for their specialist skill, and in fact they often were a second to the leader, by order of experience if not rank.
This particular squad, the Seventh Recon, was on their third patrol this week, holding position in an abandoned building. They had waited for the night cycle as per standard procedure, although it was rarely possible to discern anything resembling the Sun above the massive cover of cloud and debris. The clouds floated in the upper layers of the atmosphere for decades and showed no intention of receding any time soon. For some reason Exons seemed to be much more perceptive by day than the slight change in luminosity would explain.
So the 7th waited for the nightfall, if it could be so named, and only then did they painstakingly advance, avoiding detection, until they were at least two clicks away from the nearest Ducts access. They were on a scouting mission, but as always they had standing orders to try and ambush any lone Exon Walkers they encountered and loot it for parts. Their mission took them close enough to Hic Sunt Machinae to hope to bag at least one stray Walker, two on a good night.
At times like this, when his squad held the position, his job was to remain in cover and concealment until he was needed. So he had a lot of time to think.
So think he did.
