I agree that the RAP's are mostly garbage (but getting better, quality wise) but the ATS is hardly new. I think that the RAP system has more promise (mechanically speaking). ATS has been working on their system for almost a decade now. It still sucks and while they certainly look and feel proper now (the balance has certainly improved over the years) you can not do the proper drills on them. Also, the issues with the conveyor belt system (jamming, coming off the rollers, etc) are huge especially given the current trend toward more brittle, higher-end paint and the quality of the plastic used to make the magazines, especially the 200 rnd ones that are supposed to simulate light machine guns.
It is the drills that are important, not the equipment. We can argue all day long about whether X-gun is better than Y-gun and give our reasons why. In the end it doesn't really matter. It is not possible, at this time, to realistically simulate C-7/C-9/C-6 drills using paintball guns. I mean equipment drills and tactical procedures.
Simunition uses the same drills (yes, I know the upper receiver is modified) as the C-7, that is what is required. Using even the highest quality mil-sim paintslingers out there (which cost as much or more than a complete C-7), you are not going to teach anything that will keep them alive. Except maybe don't stand in front of the door.
I am no infanteer, but I am an avid shooter (shootist?). I am quite familiar and comfortable using my weapons in all sorts of training scenarios (live fire, ambush drills, Miles old and new, simunitions and even the militia bullets of the mid-90's ;D) and my own personal activities. But, I have far more time with a paintball gun in my hand than I have doing up-he-sees-me-down across the frozen tundra of Wainright (my knees and elbows are aching just thinking about that) or doing close quarters drills.
IMHO Paintball = dubious training value.
But can be a lot of fun.
And don't even get me started on what I think of Airsoft. To each their own.
note: Ground Zero,.....only played there once so far, not overly impressed. But thanks for looking at my profile.
Ohh, and the polite thing: MP101 has filled out a truthful profile and I saw no reason to hammer him because he does not appear to know the difference between shooting a gelatin capsule and shooting a bullet. Hence the offer of more info if he is interested. Many current 17 year old's can build you a kick-@ss gaming computer, but have never fired a rifle. Didn't mean to be condescending (but ninerD says I can be).
