All Anti-Air fire, with the exceptionion of ASF fire, can target Kennel drones.
This includes Frigates, cruisers, Flak, static and mobile, etc. All other AA.
The reason for this is because ASF deal large amounts of damage and therefore shredded through shields.
Though, a funny and cheesy strategy -at the time,- it didn't make sense for an Air-to-Air unit to deal damage to shields; Not only did it not make sense for them to shoot shields, but, that was considered 'OP' and even broken.
Again, a very cheesy strategy to deplete shields.
Hence, why their ability to target drones was removed as of... a lot of patches ago.
Even then, Kennels still are wack. But it's nice they're getting a look at.
As for them being able to reclaim an experimental, I've never seen that done with Kennel drones, so if at all, Hives should have this ability removed.
Kennels too, to make it even and fair, but, it still wouldn't make a difference to them.
