The Sentry Node Mk IV is a compact, two-meter autonomous sensor array designed for covert deployment deep in enemy territory. Its body is encased in optic and radar-absorbent plating, making it nearly invisible to conventional scans. Even in its damaged state, much of this stealth coating remains intact, masking it from all but the most thorough sweeps.

This particular unit shows clear signs of battle damage scorched plating, impact scoring, and a partially fractured outer shell from small arms fire or shrapnel. Despite these scars, its internal systems continue to function, relaying encrypted bursts of thermal and electromagnetic data. Its endurance under fire demonstrates why the Mk IV is valued: it can continue to observe and report even after being compromised.

Dropped from drones or artillery pods, the Sentry Node operates silently for weeks, feeding commanders real-time intelligence from behind enemy lines. In the field, a damaged Sentry Node may even serve as bait, luring foes into thinking they’ve neutralized it while it continues to watch from the shadows.
