MACs operate on the basis of a [[:Wikipedia:Coilgun|coilgun]]. When firing, a series of stacked coil motors are sequentially activated, propelling a projectile with vast amounts of kinetic energy.{{Ref/Reuse|WFG}} The construction of the weapon takes the form of a series of coiled conducting wires (or solenoids). When a solenoid is activated, the projectile is attracted to the coil. As the projectile reaches the coil, a second coil is activated, attracting the projectile further down the barrel of the gun. This process is repeated as the projectile travels the length of the gun, with each successive solenoid accelerating the projectile to higher and higher velocities. As such, the longer a MAC's length is, the faster the muzzle velocity of the fired projectile. | MACs operate on the basis of a [[:Wikipedia:Coilgun|coilgun]].

This process differs from that of a [[ | This process differs from that of a [[railgun]] - a similar weapon system that feeds electrical current through a projectile to accelerate it along two conducting rails. Nonetheless, railgun weapon systems are occasionally referred to as MACs - as in the case of the Mini-MAC armament of the [[M510 Mammoth]].{{Ref/Reuse|H4IGMammoth}}{{Ref/Reuse|H4EVG115}} | ||
To fire a MAC, UNSC ships must draw power from the [[fusion reactor]] into a series of capacitors, storing the generated energy for firing. As such, charging the MAC draws power away from other sub-systems such as engines. As such, a MAC can be pre-charged and fired when ready, though at the cost of power to the aforementioned systems. Without the charge being maintained, the charge level does deteriorate. However, MACs can be fired at lower charge levels than 100%{{Ref/Novel|Id=FOR17|FOR|Chapter=17}} though likely to lesser maximum velocity. Likewise, firing the weapon at lower charge rates would also allow the weapon to fire more often if needed. | To fire a MAC, UNSC ships must draw power from the [[fusion reactor]] into a series of capacitors, storing the generated energy for firing.

MACs are capable of firing a wide array of munitions, depending on bore and model.

MACs are primarily divided into two distinct classifications; light MACs and heavy MACs (also referred to as Light Coil and Heavy Coil). Overall MAC generations are denoted as Marks, with specific models given a unique identifying code. Heavy MACs appear to be typically fitted on mainline fighting vessels such as those of the {{Class|Autumn|cruiser}} and {{Class|Strident|heavy frigate}}, while light MACs are predominantly fitted on lighter warships such as the ''Charon'' and ''Stalwart'' frigate classes, ships not intended as line warships such as the ''Epoch'' class carrier or ships historically considered under-gunned as capital ships, such as the {{Class|Halcyon|cruiser}}. | MACs are primarily divided into two distinct classifications; light MACs and heavy MACs (also referred to as Light Coil and Heavy Coil).
