"Yeah, that would be the obvious drawback, but if it otherwise works I might as well load up the drone on shield stacks and cross my fingers about the diamond plating..." Design design. "List me shields."
"Brass, force. Steel, fire. Gold, light, if you care to shield from that. Bronze, energy. Copper, lightning. Platinum, freeze. Silver, stun. Nickel or nickel-iron alloy, corrosion."
Cam makes a Roomba. "Somebody try stunning that and see if anything happens."
The Roomba continues to whir around. "Great, somebody can take that home and it'll vacuum their floor." Cam designs up his drone with all the relevant shields, and then he makes it, about two feet cubed. It flies into the air and towards the Enemy.
The drone perceives:
Flying vehicles of an unfamiliar design, made primarily of metal. Humanoid figures in and around these vehicles, operating them. Flashes of light that seem to encode transmissions between vehicles.
And, as soon as the Enemy notices, a barrage of force and fire and energy.
Cam's been tracking it as it goes and patches it as it takes damage.
The drone records and relays all the flashing light. It attempts to approach a ship.
Well, that's not very nice of them. Between being able to see the mass of ships with the naked eye and the recent drone picture, Cam thinks he can just put a drone in a ship. There.
Maybe they won't notice if he puts an unshielded mic and camera in the corner over there.
But when their handheld weaponry is insufficient to damage the new drone, they panic and abandon that ship completely. It self-destructs shortly afterward. Lights flash frantically, coordinating the rest of that group as they pick up the evacuated crew.
(The feeds are projected from Cam's computer. He's not trying to stop anybody looking over his shoulder.)
"Let's try this again..." He makes another drone outside the ships to get a good enough view of another ship that he can put the unobtrusive listening stuff inside.
"Computer's analyzing what it's got of their language, but I'm going to be kind of stymied if I can't get them to talk to me later. Ever take any of them prisoner, what happens if you do that?"
"They escape the first chance they get, by whatever means. Suicide, if nothing else works. But it's rare to get the chance."
"You don't have a way to keep them from committing suicide? They have some kind of self-destruct on their persons too?"
"The last capture was before my time. I don't remember what the prisoner did specifically."
"Mmmhm." The devices report their distance, direction, and speed so Cam has a decent shot of making more things on the ship. The software takes the data and tries to separate out words and attach meanings to things.
When the feed shows each of the scattered ships contacting another group, Azair says, "Warn the local garrisons." A team member starts firing wands in presumably-coded patterns.
Meanwhile, the software learns all about Enemy profanity.
New groups of ships get spied on too! More data! (Cam's computer sprouts an extra processor insert.)
