The plasma gun emits super heated fluid of protons, neutrons and delocalised electrons (plasma basically). All of these have a mass and therefore by conservation of momentum must cause some recoil.

A laser (or light amplification by simulated emission of radiation) does exactly what it says on the tin so to speak. It is almost monochromatic light focused down a straight line. The light can be considered as packets of energy or "photons" and hence by special relativity, they have momentum. Et^2=(Mc^2)^2 + (pc)^2. The p is the momentum bit and since photons have 0 mass, p=Et/c.
So now were talking about photons with not alot of energy multiplied so that those IG can do more than damage a few orky retinas. Big energy means big momentum, from above, so we need recoil by conservation of momentum. I'm not certain of the frequency of these laser photons but i assume they are somewhere in the red end of the visible spectrum. (a comment was made earlier regarding the fact we can actually see the laser beam even though we shouldn't, well thats true apart from when you fire a laser through say a smoke machine, then you can see the laser as it interacts with smoke particles. I guess that fog of war is pretty thick.)

Hope that helps, maybe someone can play with the numbers if they're interested and see how much recoil we could get. I hope i got all the theories right too.

you did, but most people wont understand that. i keep trying to explain that the science doesnt matter as if the recil given off was as small as it was meant to be, and if there was no visible laser, how crap would the game look. imagine 30 guardsmen stationary firing nothing and killing their enemy

Dude above me (not google, guy above him) we have been throught this ffs. I explained it all before but in a more simplified version.
Can we stop this now? My brains starting to hurt and its the end of the holidays

Well ok, I just thought i'd try and explain it fully, for those who were interested. Didn't mean to over complicate it so appologies for that. Those Relic guys probably just put it in for the looks rather than the realism.

Yep, they did. Umm.. you were trying to explain it fully... you explained it and i couldnt understand it... whats all the p=z(56*g)^9H+Et!"£$%^&*(??????
Well...i think ill learn eventually...scientist man

Yes, I don't know how to do super script and sub script on here so i used the symbols which are commonly used in mathematical software (like matlab.) The ^ means to the power of. Clearly when Einstein wrote these equations he didn't consider people trying to argue fictional weaponry on a computer game forum. Again appologies for over complication.

You managed to subscript the t...

I cheated, I changed the size of the t to size 1 instead of 2.....

ok, maybe guardsmen are just so weak, light can make them take a shock, or maybe its just what you've been saying, it would look silly if someone took recoil from something that is meant to be invisible

yes, thank you. the science isirrelevant as the guardsmen would just look bad if they didnt recoil or fire visible shots
