not shore about movement rate but in terms of actions the limit on speed is 4 and the limit on mental speed is +2. these are hard limits, even if you can find 10 different +1 speed implants that all stack you still cant go above speed 4. of cause if you translate action to weapons fired down range it gets more complicated when we consider tele-operation. this obscenity is best achieved using an info morf in an idelon granting speed 4 mental speed +2 for a total of 12 mental actions/turn. each of these actions can be used not just to control one drone but a cluster of drones that are close together and attacking the same target. (close together is undefined but probably defends on the target size and engagement range. for the urban combat ranges most likely in the game i assume 1 meter.) you can easily get 8 guardian bots with 1 handed rail-guns mounted flying in close formation. a 3 round burst from each of 8 bots will flat out kill almost any target so the second burst goes to a different target. so you can obliterate 24 targets each round, single handed (sort of) as a bonus return fire has to hit each of the drones separately so even a good shot from the enemy only reduces your threat slightly, although a well placed grenade could take out an entire squad there is the issue that the guardians have only speed one so each of the 12 actions you get will have to operate a separate squad. so to do this your going to need to have 96 guardians with mounted rail-guns, and possibly some spares, and some servitor bots to reload guns. this could attract attention you don't want.
