I find it questionable that radar can be used to detect a dozen-plus people in the woods who are wearing heat-masked ghillie suits and the like, and that the Antarcticans could just advance on them across the field between the tree-line and the structures with impunity. If anything, the drone would be picked up on. Not the Sons of Liberty's favorite infiltrators and bushwhackers. The drone is the only thing making any sudden movements, and that's a dinner-plate sized robot about two hundred meters up in the air. The rest of them are hundreds of meters away in the woods. They're flanking these guys, who are most certainly watching their rear and flanks, in white armor. That's not going to work.
