chinese drone swarms can be used to scout out areas and overwhelm enemies defenses using weapon attachments fpsrussia style   jmk2fgju&t=229s&ab_channel=fpsrussi a have them enter dugouts and trenches airship borne drone swarms target power grid water plants and public transportation as well as motorway entry and exit points and gas stations  or just regular troop supply and logistics related targets or infrastructure or areas on which said logistics & supply depend upon  the drones having already proven themselves useful in human rescue missing persons and manhunt scenarious in rural and forestry regions semi forested and wooded regions the drones could be made to use a smaller round (say 22long-rifle) that can be carried in larger amounts in a drum mag to reduce space taken up outside the silhouette of the drone a simple blowback style firing mechanism would suffice a vertical ejection port as there is no need for a left right differentiated port this can be stamped for ease of manufacturing as well as most of the rest of the parts most parts could be sourced from existing firearms manufactured otherwise something like a glock with a switch or some similar such thing could be used to maintain a high fire rate while still having a large ammo capacity as seen in the american 180 (1200 round/min (.22 long rifle) 1500 round/min (.22 ilarco)) using the drone collision avoidance program and swarm movement technology to avoid moving into lines of fire  a shortened barrel can be used in combination alongside a mechanism which can be hidden underneath the drone the mechanism of the firearm used (if a custom design is not used) can be taken apart and reassembled to fit a square space along side the barrel with the drum magazine being located directly beneath the mechanism and barrel or you could follow a simpel solution as seen in the following videos where a clock is simply dropped into a police breaching robot
