===Actions===
"Action" refers to how ammunition is loaded into the weapon.

*Single-shot: The first and oldest of all; a single-shot weapon is when users manually load rounds into the chamber. This can be anything from loading a new round, cocking the weapon every shot, or pumping the action.
**Muzzle-loaded: The earliest form of how weapons were loaded. This meant you had to load a new round directly into the muzzle, which is where the bullets come out. In its earliest form; muzzle-loaded guns were complicated to arm; you had to fuck around with a wad, powder, and slug. In the heat of battle, you had to ram these down the barrel of your gun in the correct order, light the wick, then aim before the gun goes off. And you had to do all this while standing in the open within firing range of your enemy. Still in use because many jurisdictions have a muzzle loading only season and such obsolete arms are subject to fewer legal restrictions in general.
**Breach-loaded; An upgrade over muzzle-loading and developed shortly after cartridges were invented; breach loaders are where the back of the barrel can be opened so that you can load a new round into it. Many muzzle loaders were converted to breech loaders in workshops near the end of the Industrial Revolution. It is still a popular setup for multi-barreled shotguns. Certain revolvers are breach-loaded as well, but given the size and design of the revolver, this gives them a notable weak point at the top of the weapon where the parts connect together. Most come in flavors such as break action (popular with simple shotguns and flare pistols), trapdoor mechanisms, rolling blocks, falling blocks (attached to levers), or bolt action.
**Bolt-action: This type of action is where you pull the charging handle of a weapon, every time you shoot so that a new round can be chambered. They come in two varieties: faster but weaker locking straight-pull bolts and slower but stronger rotating bolt actions. Originally starting off as single shot rifles, they eventually added magazines to reduce the amount of loading required once smokeless powder was used. These were pretty popular in WW1 and continues to be used today for precision rifles and discount anti-material rifles due to their simplicity and strength.
***Needle Rifle: An early precursor to the bolt action from the 1840's with the Dreyse and Chassepot rifles. Unlike its grandchild in WWI, these used self-contained paper cartridges where the primer is on the tail end of the projectile and the gunpowder is sandwiched between the primer and the rest of the paper cartridge. To ignite the gunpowder, the bolt's firing pin actually needs to puncture the cartridge from the back with a needle and hit the primer. While faster to fire at six to fifteen rounds per minute compared to a regular muzzleloader, their needles warped after repeating shooting and had to be replaced. And in the case of the Chassepot, their rubber seals in the breech would deteriorate and require swapping. Once metal cartridges were invented a decade later, the needle rifles were replaced with fully fledged bolt action rifles as we know them.
**Lever-action: The cool kid of the single-action club; lever-action weapons are those where you have to use a lever to chamber a new round, which was usually mounted near the trigger. Great for shooting from horseback, not so great lying on the ground. This type was made popular by Winchester during the frontier age of the Wild West and even more by Arnold Schwarzenegger when he used a lever-action shotgun during Terminator 2. Tend to be chambered for pistol cartridges and intermediate rifle cartridges because its metalurgy and action weren't strong enough for full rifle cartridges till the 1890s, when bolt actions had started displacing it, and tube magazines requiring flat nosed rimed cartridges while market forces limit them to cartridges that are still made (a crossover that's essentially just .22lr, revolver cartridges, .30-30 and .45-70).
**Pump-action: A pump action is where you had to pull the "pump" of the weapon to cycle a new round. This is the most common action used by shotguns. A few rifles used this setup as well (but only with round bullet heads as pointed bullets have the risk of setting off the primers), and there is one instance of a bunch of madmen creating a pump-action 3+1 (three in the tube, one in the chamber) 40mm grenade launcher. 
*Automatic action/Self-loading: Unlike single-shot weapons, it uses gasses expelled by the cartridge or recoil to power a mechanism that automatically chambers a new round after each shot. Generally speaking, the semi-automatic to fully-automatic action is determined by the trigger sear, which may either inhibit the hammer from hitting against until the trigger is let go (semi-automatic), stops firing after a certain number of rounds have been fired (burst-fire), or continuously fires until ammo is expended (fully automatic).
**Semi-automatic: A semi-automatic weapon is any weapon that can fire after every trigger pull, with the user only needing to work the action after reloading a completely empty gun. Most handguns and many rifles are semi-automatic.
**Burst-Fire: A setting sometimes included on automatic weapons, each trigger pull fires several rounds before stopping automatically. Fully automatic fire in a handheld gun tends to very quickly go off target due to muzzle rise, but by limiting fire to a controlled burst, the gun is easier to keep trained on target. The main purpose for this setting is to defeat personal body armor; many types of armor such as ceramic inserts are only designed to reliably stop one rifle bullet, not a close grouping of several hits in succession.
**Fully-automatic: A fully-automatic weapon is any weapon that can fire automatically, so long as the trigger is depressed, rather than pulled each time like how semi-autos work. Automatic weapons tend to be banned for civilian use outside of firing ranges and are only available to military even in countries liberal with gun rights.
