I proposed the options to the team.
The decision of the team was that the only weapons allowed on the field with an fps greater than 400 will be bolt action rifles. Single shot bolt action sniper rifles.
In addition, the engagement distance will not be less than 100 feet.
Rifles set to semi-auto are not included in this allowance.
The explanation given was this:
A sniper, with that high powered of weapon, should be able to make their action count by a single shot.
The action of a semi-auto weapon is to put ammo down field until the target is eliminated, as fast as the operator can pull the trigger. This type of semi-auto action can be used to "walk" shots into the target, or sweep several targets in close proximity. Continued fire is also often the result of the operator not initially hitting the target. The result is that the operator's target may be hit repeatedly by a high powered weapon, in a action that resembles a Rifle Marksman rather than a "Sniper".
By limiting operators to weapons that are bolt action ensures that single intended aimed shots are being performed. The operator must make every shot count. The result of a miss is that the operator must chamber another shot, taking time to reload as well as reacquiring the target in his sights. The benefit awarded this type of operator is that the weapon they are using is allowed to fire at a greater fps to increase range. This extended range also benefits the sniping operator through concealment when the shot is taken at distance.
I do want to thank everyone for the inspiration which brought the opportunity for discussion to clarify this topic. It is something that needed to happen so that a clear understanding of the rule can be issued. Diamond Corps will continue to define a "standard" set of rules in accordance with the Airsoft community.
Although not up for debate, your opinion on this matter is still important.
"Few operators have the patience, skill, and equipment to properly perform the role of "sniper". - Opinion of one Operator.
Many of the operators on the Diamond Corps team have upgraded full length rifles (510mm barrel length or greater). I often describe these as "long rifles", to differentiate them from carbines (which are generally around 363mm in barrel length).
Of the AEGs Kattiana owns, one is a scoped, upgraded CA25 with a 651mm barrel. It fires both semi and full auto, holding over 400 rounds in the magazine. She likes to "nest" in cover and kill her targets with single or double shots at distances over 220 feet. She is an exceptional "rifleman". Where she this proficient in the USMC she would be a "Marksman".
I leave you this example as basis for your comparison. Thank you.
