AI Patrols

AI-controlled vehicles roam the map. The patrol helicopter tours the whole of it on its routes, one at a time; the BTR drives the roads on patrol. Both are events rather than scenery: they come and go.

Radio intel. Patrols, wrecks, crash sites and airdrops show on the map for your whole group when anyone in it carries a working radio. Walkie-talkies found in the world always come with a battery. Groups.

It steers clear of the hub (400 m around it) and of every trader (150 m).

The BTR patrol runs one at a time and returns 1 h after it is destroyed.

The helicopter#

Balanced for a squad with rifles, LMGs or snipers — hard to solo, and it shoots back with its turret. No missiles. It leaves you alone until you open fire. Down it and there's no replacement for a while; the wreck drops five loot crates and is defended.

The BTR#

The BTR is an armoured car. One RPG or LAW rocket destroys it outright, and grenades work. It shrugs off rifle fire, so bring rockets. It runs for about half an hour, then leaves the map for an hour. It never leaves in the middle of a fight: while it is under fire or players are close, it stays until things are clear, for up to another half hour. Its wreck always drops three crates.

What the wrecks pay#

Endgame plate carriers and helmets, GPNVG-18s, top-tier rifles, medical and barter, with a small chance of an anti-materiel rifle: about 4% from the helicopter and 2.5% from the BTR. Both can also turn up a coloured Lab keycard, rarely. Both wrecks carry anti-tank — a PG-7 rocket, a LAW or a reusable RPG-7 — which is where the launchers for raiding come from.
