I like this idea

What he said. BTW best quote ever.

But if they are stunned, how are they going to get away? And as far as the commander goes, perhaps you could carry him over your shoulder and either he will disable your secondary weapon slot (one arm to hold him) or both like in the Halo series (both arms).

You can't freeze people in BF2/2142 anyway. It would simply make them lose sprint and vision for a bit. And the commander carrying thing isnt possible with the engine, unfortunately.

Stun batons are also in..whether they actually stun you atm i dont know but they look cool.

Well the E-11 had different modes: it could just blast somebody, like u see alot in the movie (if they hit somebody ), but they can also set the E-11 on stun to capture somebody, like they did with Leia, but instead of a red laser that comes out of the E-11, they appear as blue circles. Another more heavy mode of the E-11 was actually vaporize somebody, but was practually never used, cause it took alot of power to use this mode

No way. And theres a good reason why:

Kidnapping - it happens already in BF2, you keep reviving someone and killing them (takes 2 or more people), forcing him to leave the server. With stun, you can just keep stunning them without ever killing them. They're helpless.

Another way to do this would be (in fact you could be doing this already) to give both teams stun batons instead of knives (I believe the rebs had knives before); and the advatage of creeping up behind someone is that you can stun them (with the effects above). Of course, when you stun them, you get a dog-tag saying "Player X got stunned!" which you can proudly display on a forum. Once they're stunned, you're free to kill them. This would be useful if you sneak up on groups. You could stun one and shoot the other, then reload and shott the stunned guy.

I think I'm missing something. That would effetively just be a short range version of what Arc is suggesting above. How would that stop someone from "Kidnapping" as your putting it?
