On the pic I posted, the thingy in back under the EO ball is a drone radar, the main sensor for the anti-drone mission. A variety of weapons are available; the autocannon, an EW scrambler somewhere, and a suicide anti-drone drone launcher somewhere else.
The Stinger can be employed too as I believe it was/will be certified for anti-drone ops but it's more for the traditional VSHORAD role which this vehicle can tackle too.
Amazing all the stuff they're throwing on the M-ATV these days.
