A large railgun type weapon frequently used in the Halo universe. Sizes vary, from a handheld one shot anti-personnel weapon, to the main weapon of most of the frigates, destroyers, cruisers, etc (e.g UNSC Pillar of Autuum) to the largest, most powerful type, the "Super MAC", a massive railgun mounted on a space station capable of firing its projectiles at speeds close to 4% the speed of light. (e.g. Cairo Station, Halo 2). Said projectiles are made from extremely dense metals, such as depleted uranium, and despite the disadvantage of having to charge the weapon for every shot, the sheer kinetic impact velocity of these projects can do extreme damage to most targets.
“That Magnetic Accelerator Cannon (MAC) gun can put a round clean through a Covenant Capital Ship" - Sergeant Major Johnson describing the sheer firepower of Cairo Station to the Master Chief John-117.

Get the acelyn mug.An example of Beare's Law of Accelerating Catastrophe at Sea - BLAC.
Imagine you are at sea and sailing along nicely a few miles off the coast of Corsica. You have the Genoa poled out and are running downwind. You are single handed. You pop down below to make yourself a cup of tea. Everything is fine. All of a sudden the wind shifts and you gybe. The pole slams across the forestay bent; the genoa is backed and the pole is trapped under the sail. As the boat lurches you are scolded with coffee. You rush on deck to sea the wind picking up and the boat floundering.
You are confident you will soon bring things under control. However, the wind is gusting alarmingly. A squawl from the hills. You cannot get the whisker pole off to furl the sail. You look up and in horror you see a ship coming at you dead ahead. The wind gusts and the boat is knocked down. You slip and land hard on deck bruising your arm.
And so it accumulates as you experience Beare's Law of Accelerating Catastrophe at Sea - BLAC.
