Generally most armed forces and police units do not use paintball gear for training (as they use Simunition, a type of frangible projectile similar in concept to paintballs but are designed to be used in real-world firearms). However in some cases there are instances the US Army is shown in some documentaries to have been using Tippmann's "US Army" branded paintball markers.
No. There are no urban areas that allow paintball.
Yes, all brand paintball guns use a tank or other source of pressure.
Not completely sure how you could use a balloon instead of a paintball marker. Though paintball is known for its guns therefore no.
Nearly everything. Paintball guns are fired through the use of air or CO2. Also they shoot only paint. bb Guns shoot pellets, and look completely different then most paintball guns.
If you aren't mature enough to play paintball, you aren't mature enough to use firearms. There is no way you can confuse paintball or vidoegames or airsoft for what you should be doing with actual guns, unless you are not old enough to use guns.
Paintball guns are not classified by their roles. If you ask the ref if you can use two guns that's fine. Having two guns (with basically the same range) is a waste and will slow you down.
No, you should use only paintball specific of air tool lubricant.
Most paintball guns use an above hopper instead of magazines or clips like firearms. The standard hopper holds 200 rounds. Most magazines for paintball sim-markers are 30 rounds. No paintball guns use clips.
Yes, with the very few exceptions of certain older automatic mechanical guns.
Actually yes in some cases. Kingman released two new paintball pistols, the Chaser and the Eraser. These have been very popular for hand gun training not only in the military but in law enforcements.
It is like paintball mixed with laser tag. Same rules as laser tag but you use paintball guns with rubber ammo.
Yes, infact it is recommended.
