Lantean Drone Weapons

Ive never told anything regarding Lanteans nor im 100% sure if their weapon, small drones exist, but i feel that i have to tell something in this matter, cause i got rather big knowledge regarding army rules that where present those days.
Weapon of Lantean, self-guided Drones are weapon rather terryfing. It can wreak Havock among the enemies, but its also showcase of some sort of status. First of all, its not a direct weapon. So its not a weapon that would damadge an enemy directly like a Kinetic Cannon. Drones are simmilar to rockets, which is guided only by a computer, not like a cannon manualy.
Lanteans havent got in their arsenal any type of Cannons, only a drones that can act as self defence system, not offensive weapon.
In the end, Lantean weaponry i would rather clasificate as self-defence for a civilian. Why ? Those drones havent got on board any type of warhead, only atacking by kinetic energy which is formed by impact into target. Its rather a sign of a civilian weapon for a self defence. Today we could see similarity in windcheater and its usage.
So as we can see, Lanteans werent Army Presonel, so guarding the borders was a task for a other nation which was better equiped for this task, than the "civilian-looking" Lanteans.
