The M31 Assault Plasma Rifle is a directed energy weapon that uses a superheated ionized gas called Plasma instead of projectile ammunition. The weapon has a power output of 100-150 KV @ 2~3 dA, and can fire 360 to 540 rounds per minute. Unlike the M31 assault plasma rifle is capable of semi-automatic and full automatic fire. Taking fire from the M31 can cause severe second, third, and in some cases, fourth-degree burns (a fourth-degree burn completely burns away all flesh, leaving only bone tissue). due to the faster rate of fire, injuries inflicted to the victim are severe third-degree burns, with the wound being cauterized instantly upon impact. Even near misses will produce severe burns and heat trauma.
Should the plasma impact an object, the impact can create fragments that may come into contact with a victim, with a crippling or lethal effect. The M31 Assault Plasma Rifle will kill a light or non-armored target. Firing the weapon for over-extended periods of firing can overheat the weapon, causing it to become unusable for a short period of time. The Plasma Rifle is a close to medium range weapon, and as such can inflict very high damage at range. The Plasma Rifle can also be used at long range if the user fires slowly and aims carefully by leading the target. The rifle is extremely efficient at killing "soft" targets, while doing lethal amounts of damage to a heavily armored target. Enough infantry equipped with M31 Rifles can halt enemy infantry advance with its ability to deliver harassing suppressive fire.
The M31 Assault Plasma Rifle, when fired continuously, overheats very quickly because of the rapid cycling, loading, ignition, and release sequence of energy; to prevent the weapon from being damaged. The M31 temporarily shuts down and vents out the excess heat thought small vents on the top front of the weapon once heat has been dissipated the weapon will then reactive. This process leaves the weapon inoperable and useless. Careless infantry who are not aware of the function of the M31 Assault Plasma Rifle can get themselves killed because of this. when the battery is depleted, the battery must be change with a fully-charged one.
At 10% energy level, the M31 assault plasma rifle will begin to misfire, this is due to the battery's inability to deliver enough energy to start and complete the ignition and release phase of operation, hampering the operator's use of the weapon. Although the Plasma Rifle can strike a target at longer ranges, it is not suited for long range combat, due to two distinct properties of the weapons operation. The first is the rate of thermal expansion which is determined by the rate of the bloom of the bolt. The second factor is speed: the faster the bolt goes, the farther the bolt will travel before the magnetic field begins to weaken, causing the temperature of the bolt to cool before the magnetic field becomes unstable and finally dissipates. The bolt also loses velocity and kinetic impact with longer travel distance.
There are three different models of this weapon.
Type A: This is the standard model and it only has the standard foregrip. This is the model most commonly given to lower ranking infantrymen and base security personnel. This is also the only model that civilians have access to and allow to own (though the civilian Type A/C model has a much lower power output and is single file only.) But the Type B and Type C models are for the military, police forces, and private military companies only.
The Type B: This model has a build-in three shot 40mm grenade launcher. Which can fire three shots in semi automatic mode and allows the shooter to maintain eye contact with the target during an engagement. This significantly increases the probability of hit (pH) and probability of kill (pK). Further, a semi automatic capability enables rapid multiple shots to first penetrate cover, such as a light armored or soft skin vehicle, window or door opening, then incapacitate targets inside. This capability is simply not achievable with a single shot system.
The Type C: This model has a build-in K1 Plasma Bayonet. the plasma blade cuts through most substances without resistance. It leaves cauterized wounds in flesh, but can be deflected by another plasma blade type weapon, or by energy shields. Some exotic plasma blade-proof materials has been also used in certain solid shields, but these types of shields tend to be very expensive. So other solid shields are usually given a energy and heat resistant coating which is much cheaper, but will only last for certain time. An active K1 Plasma Bayonet gives off a distinctive hum, which rises in pitch and volume as the blade is moved rapidly through the air. Bringing the blade into contact with an object or another plasma blade type weapon produces a loud crackle. The K1 is battery powered, requiring the user to change with a fully-charged one.
