'''Knockback''', or push force, is the movement of a player caused by an outside source. When taking [[damage]] from any source, a player experiences an amount of knockback that generally scales directly with the power behind the attack. For example, a point-blank [[Scattergun]] blast pushes its recipient farther back than an uncharged [[Sniper Rifle]] shot. While most weapons inflict minor knockback at best, there are quite a few exceptions that inflict significant knockback and can have a dramatic effect on the battlefield. Significant sources of knockback instantly interrupt any animations the victim is in, including [[taunts]] and consumption of a [[lunchbox]] item. The [[Heavy]] takes 50% less knockback from damage sources except for [[Sentry Gun]] bullets and [[Scorch Shot]] flares.<ref>ApplyPushFromDamage function from game/server/tf/tf_player.cpp</ref>

'''Knock back''' is a side-effect of some weapons that pushes a player away from the source of the knock back. In Team Fortress 2, knock back varies from very slight (only preventing you from moving forward temporarily), to extreme (launching you several feet into the air). Knock back can be useful strategically, such as when [[juggle|juggling]] opponents. Nearly all weapons provide knock back which scales up with the attack's damage, but the effect is very slight and hardly noticeable until the attack's damage approaches ~100. This can be changed for functionality purposes, like the powerful knock back possessed by the [[Force-A-Nature]] and [[Sentry Gun]]s.

For example, the [[Thermal Thruster]]'s landing knocks back surrounding enemies, while every [[Weapons#pyroprimary|primary weapon for the Pyro]] (except the [[Phlogistinator]]) can use its compression blast to knock users back.

“ ”

Knockback, or push force, is the movement of a player caused by an outside source. When taking damage from any source, a player experiences an amount of knockback that generally scales directly with the power behind the attack. For example, a point-blank Scattergun blast pushes its recipient farther back than an uncharged Sniper Rifle shot. While most weapons inflict minor knockback at best, there are quite a few exceptions that inflict significant knockback and can have a dramatic effect on the battlefield. Significant sources of knockback instantly interrupt any animations the victim is in, including taunts and consumption of a lunchbox item. The Heavy takes 50% less knockback from damage sources except for Sentry Gun bullets and Scorch Shot flares.[1]

Weapons

Several weapons deal extra, increase, or decrease knockback. For example, the Mantreads reduces knockback from incoming damage and airblasts, while the Shortstop increases the knockback from those. Some weapons have a special feature that deals knockback with little to no damage. For example, the Thermal Thruster's landing knocks back surrounding enemies, while every primary weapon for the Pyro (except the Phlogistinator) can use its compression blast to knock users back.
