1.Okay. Sorry, but I don't understand what you want explained.
2.Well, presumably if we control the battlefield this stuff isn't as important. But mobility is still useful in defense. Take an instance of two squads shooting at each other in an urban area. One sends a QC into the air, so it's effectively flanking them vertically. Or if one area of the battlefield needs reinforcments quickly, several of these can be diverted much faster than land vehicles, unless there's a nice road system or something. Mobility isn't always useful, but those are exceptions.
3.You still have to get the rocket to be within a foot or two of the arm, which is still a small target. That's moving around. I also doubt rotorstrikes would set off a rocket- they're not machetes, and rockets are usually idiot-proof, so they don't just explode under minor impacts.
4.What -exactly- am I not explaining? I've been trying to go into as much detail as I can without hogging the whole thread (And I think I failed here). As far as nukes... I think that's always gonna be a vulnerability. I'm currently arguing for an infantry support drone, similar to the RT's role.
5.A rotor's speed is limited by the speed of sound, 760 MPH, at the tip of the rotor. High-performance copters going at max speed are really the only things that will make the rotor go that fast. For comparison, 20mm Vulcan* has a muzzle velocity of 2315 MPH, and is 102mm long. The rotor probably occupies 5% of the space that it can occupy at any particular time. Do the math.
*Gauss rifles fire a 20mm round and can explode the torso of their target. I figured this is a fair equivalent.
6.Welp, it depends on exactly what it hits. Assuming you didn't armor it so you'd have maximum speed, stuff breaks. If it hits the CPU, you killed it. If you just hit the gun, you disarmed it. Note that you had to hit a thing that's two or three square feet, assuming this thing is huge, and it's moving very fast and unpredictably. If you did armor it, well, it depends on how well you armored it.
7.Ahh, no, with pretty big quadcopters. Like, four feet wide. And under conditions that really would screw them up, like 50 MPH winds. :I
8.Yes.
@AoW talk
Miya traded the integrated coilgun and tesla saber for a universal manipulator. Kept the cutting laser though.
@Anti Materiel rifles would be more useful than tanks
The irony of this statement... you realize modern "anti-materiel' rifles fire 12.7mm rounds? Gauss rifles fire 20mm.
