===Classes of Not Actually Tanks=== 

Despite having treads and a gun, the following vehicles are not considered tanks. The difference is that tanks are designed for frontline combat, while other vehicles with treads are designed to carry and support infantry (APC/IFV), bombard enemy positions with heavy artillery (SPGs), or act as general support weapon systems. Many of these vehicles are light enough to be deployed by aircraft, giving them an edge over tanks in response time to emerging threats. If it isn't a purpose built chassis, they are frequently based on the previous or current tank being used to simplify logistics.

*'''Armored Personnel Carrier''' APCs are light vehicles designed to carry infantry and not much else. They're usually given a heavy machine gun to support the infantry they're carrying into battle and to defend itself, but they're highly unlikely to have more firepower than that. They're designed to protect against small arms fire, not tank shells. Unlike IFVs, APCs are not expected to fight on the front due to their lackluster protection and armaments. However, they're sometimes also amphibious, something that the vast majority of tanks are not, allowing for both seafront assaults and quick getaways down waterways. Don't expect anything bigger than a HMG (that being under 20mm, usually also under or equal to 15mm) and a grenade launcher. Very rarely a low caliber (20 to under 25mm) autocannon may be present. May have a couple ATGMs (Anti Tank Guided Missile) to suppress the enemy but it isn't designed to stay in a firefight, an APC is first and foremost a transport.
Examples: [[Rhino]],  [[M113 Armored Personnel Carrier|M113]], Namer (notably, it is based on the Merkava, an MBT, and has unusually tough armor)

*'''Self-propelled gun (SPG)''' Vehicles armed with artillery weapons designed to bomb the enemy back into the stone age, ranging from howitzers, mortars, or missile systems. Typically built similarly to tanks, but sacrifice armor for their heavy guns since in normal circumstances they should be too far away to get shot at directly. Not to mention that some artillery pieces have a minimum range where they can drop their payload; thus, the SPG needs to put some distance between them and their target so that they can be in effective range. The advantage to having such artillery on an actual vehicle rather than being stationary, is that counter-battery fire can threaten static guns, while mobile guns can safely get out of the danger zone once they've delivered their payload. Self-propelled guns typically carry a 150+mm Howitzer, much larger than what any proper tank would carry. While mobile rocket platforms such as the [[BM-21 Hail]] or MLRS are more popular than Self-propelled guns and are capable of absolutely soaking an area in rocket spam, the SPG has the advantage of being able to sustain fire for longer periods of time. Besides that, most SPGs can also depress the barrel enough to engage something directly which can be useful in some situations (avoiding collateral damage, for instance). Do note that standard operating procedure for SPGs is to <s>leg it like a little bitch</s> tactically redeploy if the enemy close on their position: even if they carry a big gun, they are not front-line capable vehicles. Direct engagement is avoided even if a huge shell will ruin a punk's day just fine. May have a machine gun or two just in case (and theoretical anti-air in older models, mostly enough to scare them off with a burst of tracers), or an autocannon if the armed force is particularly passive aggressive and has money to blow on useless overkill.
Examples: [[Basilisk Artillery Gun]], [[M109 Howitzer]]

*'''Self-propelled anti-aircraft gun (SPAAG)''' Tank-like vehicles armed with weaponry designed to shoot aircraft out of the sky to provide mobile anti-air cover. There are only three real ways to shoot a very fast moving aircraft out of the sky. [[Dakka|First you can use as many rapid fire guns as you can to fill the air with as many bullets as you can and hope for one hit]]. Second, you can fire one big shell up into the air and at a certain height have it explode spraying shrapnel around it self to score the one hit you need, this are known as Anti Air Artillery, and are known in the English world by the name the Germans used during World War 2, flak. Both have been superseded by AA missiles which can track a target and put that shrapnel warhead closer to the target than just guess work and a slide rule can. Others use both guns and SAMs. As a sidenote, flak tanks (and half-tracks) equipped with heavy machine guns and small autocannons have a nasty reputation as being infantry trouncers as multiple barrels spewing lead at high speed will turn soft ground targets into mulch very quickly. Indeed, both the M19 MGMC and the M42 Duster were primarily used in this role despite having been envisioned as point-defense SPAAGs. That role had something of a heyday between WW2 and Vietnam, with the quad mount 50 cal M45's being nicknamed Kraut Mover and the twin 40mm's of the M42 being used to lumberjack VC hiding in treelines. Modern variants mostly have guided missiles and the BRRRRT variants are usually not mounted on tanks.      
Examples: [[Hydra Flak Tank]], [[ZSU 23-4 Shilka]]
 
*'''Infantry Fighting Vehicle''' Known as IFVs, these almost-tanks are capable of transporting infantry forces, while being armored and armed enough to be of support to the field, unlike light tanks. However, unlike true tanks, IFVs can't be expected to stand up to enemy armor. Modern IFV's can have anti tank missiles, but with their tin can armor, going toe to toe with a main battle tank is suicide and so it supports regular tanks or takes on enemy armor in emergencies. While APCs and IFV can share similar roles and armaments today, the main way to distinguish them is with their main gun: anything that has a main gun smaller than 25mm is classed as an APC, and anything higher is an IFV. IFVs are designed to stay and fight (though not toe to toe with enemy tanks) and act as direct fire support.   Effectively, when comparing a squad with an IFV vs a squad with an APC, the later is an infantry squad with a transport, the former is a (light) tank that can dismount some of its crew.
Examples: [[Chimera Transport|Chimera]], [[Razorback]], most [[Land Raider]] patterns (albeit with the difference that they can hold their own against regular tanks just fine), [[BMP]], [[Bradley_Fighting_Vehicle|M2 Bradley]]

*'''Armored Reconnaissance Vehicle''' In some ways they can be confused for IFVs in that these vehicles are similarly equipped and focus on mobility, and may even have limited troop capacities. But where they mainly differ is in doctrinal use: Armored Recon is mainly used to provide independent support to a recon team rather than support front-line troops. As such, troop carrying capacity isn't as necessary if it has any at all. See below the Infantry vs Cavalry Tank distinction as it can apply here as well, since modern cavalry units use such vehicles. Some IFV's share a base chassis with ARVs , those ARVs are usually called Cavalry Fighting Vehicles (CFV).
Examples: [[Salamander Reconnaissance Tank]], [[LAV-25]], [[M113 MRV]], [[Bradley_Fighting_Vehicle|M3 Bradley]] 

*'''Tank Destroyer''' Tank destroyers are specialist armor designed for one thing in mind: knocking out armor and not much else. Some are turreted, and some aren't. Most modern ones use guided missiles, all historical and some modern use cannons. What makes them not tanks is a matter of technicality. Tanks are designed for general military purpose (so useful for a range of tasks) while tank destroyers are for only one thing, destroying armor (especially on vehicles). After World War 2 we figured out that since tanks fought other tanks so often anyway tank destroyers don't really make sense so we upgraded the guns on regular tanks. While the role of “Light Anti-Armor Vehicle” was taken by ATGM carriers, which are mostly modified APCS and IFVs, have the ability to kill tanks while being very mobile and easy to transport. A handful of cannon-armed Tank Destroyers still exist, some tracked, others wheeled, but they're a rare breed. They tend to be considered for use with airborne troops in need of anti-armor capability (since a proper tank tends to be too heavy to airdrop) and for certain strategic mobility concerns, usually built by replaced IFV turrets with a cannon equipped one, practically making a wheeled light tank.

*'''Assault guns''' Similar to tank destroyers, assault guns differ in one important way: instead of an anti-tank gun, they're armed with a anti-building weapon, frequently a howitzer. These tended to be fairly big and fairly heavy compared to SPGs, because they're made to get in close to heavy fortifications. After World War 2 assault guns became light air-dropped weapons to support airborne troops if they encountered hard targets. They are comparatively very rare in modern orders of battle. Most that remain are in the Third World (usually WW2 Soviet vintage, they made a LOT of things), but some nations use IFV's equipped with cannon turrets, effectively making wheeled or tracked tank destroyer assault gun hybrids.
Examples: [[Vindicator]], Churchill AVRE

*'''Flame tank''' a tank (going from tankette to heavy, all types were used in WWII) with a [[meme|werfer zat werf flammen]] instead of a big gun as main weapon. Only used in the 1920s-1950s as they were quickly rendered obsolete (it was more cost-effective and just as efficient to have standard tanks have a flamethrower as a coaxial gun), though incendiary weapons of various sorts are still used today, mainly in artillery roles. Typically unpopular with both forces using and opposing them for many reasons: the implications of this weapon were very harsh as the typical man-portable flamethrower has a range of 60 meters max (video games lied to ME?!) and their heavy mechanized versions could reach most of a quarter mile with their concentrated hydraulic spray of diesel fuel. Flame tanks were supposed to start with a "Wet fire", basically spraying the fuel without igniting it into bunkers or fortifications to get enemy units to realize just how hard they were fucked, really weren't protected from the coming blaze at all and in turn they would surrender before being cooked to death. Which a vast majority actually did when '''''hosed with gasoline'''''. The problem was that, due to either open fighting, soldiers that just wouldn't surrender or sadistic crews/commanders, the weapons were often fired outright the first time around to horrific physical and psychological impact on both sides - burning, screaming soldiers, the fumes making crews sick, thick diesel smoke inhalation or oxygen depletion asphyxiating those in poorly ventilated areas (especially caves in the Pacific Front) and the smell of burnt human flesh permanently seared in their minds meant that instant life derailing post-traumatic stress disorder was a very common side effect of witnessing a flame tank in action. Another was that flame tank crews that were captured were usually subjected to torture and summary revenge executions. In the end, flame tanks are remembered as a job nobody wanted to do, an enemy nobody wanted to face, a weapon that accomplished little that soldiers using the man-portable variety (which already had a bad rep' but was begrudgingly tolerated by soldiers as tactically necessary to avoid chemical warfare, nobody in their right mind wanted to clear caves out directly) could not do and pushed the propaganda and soldier's beliefs forward that the enemy truly were barbarians and made of evil, all pushed ahead because a Commissa -- I mean General far removed from the field said they were necessary. Real life Grimdark indeed.

And finally, something of a special case:

[[File:Hilux.jpeg|200px|thumb|right|What a "technical" looks like over history, as demonstrated in this meme photoshop<ref>We'll ignore that there's only one actual Hilux in this "ad", for the sheer joy of imagining Toyota advertising in glossy magazines to warlords</ref>.]]
*The '''"[[Pickup Trucks|Technical]]"''', also known as "non-standard tactical vehicle" or "light improvised fighting vehicle". Essentially, just a pickup truck with a machine gun (or some other semi-portable weapon, like an anti-air or anti-tank weapon) mounted in the back. Originally named "Technical" because some of the first notable versions were hired by charities operating in very dangerous territories in Africa, and since said charities were forbidden from calling them "mercenaries", they euphemistically referred to the money used to hire them as "technical assistance grants". The Technical's most shining moment was probably the "[[wikipedia:Toyota War|Great Toyota War]]" of 1984, where Technicals, armed with precision anti-tank missiles from France, beat a Libyan force with actual tanks. [[Pun| Technically]], [[counts as]] an Infantry Fighting Vehicle, but fills a distinct, unique role in modern warfare: the cheapest, frequently fastest to make<ref>And in mountainous terrain, sometimes the fastest full stop; one of the reasons U.S. Special Forces used technicals in Afganistan was because a 4-wheel drive truck can frequently get into places no other vehicle can.</ref> IFV available to just about anybody with access to weapons and trucks, useful for projecting power and supporting infantry on the quick and cheap.
