Convoy Reconnaissance

I advanced past the unlatched patio screen, descending the concrete ledge onto the exterior flagstone path. The sector is expansive. At coordinate zero-two, a dark, moving perimeter line intersected the pale stone. I halted immediately and assumed a low surveillance crouch. It was not hostiles. A convoy of small black insects was advancing in unbroken single file along a hairline fissure. Zero erratic deviation. Flank spacing maintained at precise half-millimeter intervals. They transported organic cargo toward an unmapped subterranean depot. I remained stationary for six minutes, monitoring their flawless route discipline. Local transport efficiency verified. Reconnaissance complete.
