So, you and your squad are off on a mission. You've got armour, guns, grenades, etc. - everything you need. But there's a catch - on this mission, there is likely to be little cover. What do you do? Take some of your own with you, of course!

Deployable Cover can be anything from an energy barrier that deflects bullets to a big pavise that can be planted into the ground to protect you from arrow volleys. Often, the deployable cover won't be as durable as natural cover, eventually getting destroyed after it is shot enough (though, in the case of an energy shield, it may reactivate after a short time). It will, however, last indefinitely if it is left alone.

[[LuckilyMyShieldWillProtectMe If you carry the cover with you whilst making use of it, then it's closer to a shield]].

[[IThoughtItMeant Nothing to do with]] [[ContemptibleCover deplorable covers.]]

[[folder:Anime and Manga]]
* Planet Defensors in ''Anime/MobileSuitGundamWing'' can be deployed to form a DeflectorShield.
[[/folder]]

[[folder:TableTopGames]]
* ''{{Champions}}'' supplement Gadgets! The Force Wall Generator was a device which, when placed on the ground and activated, would create an energy shield to block incoming fire.
* ''{{GURPS}}: Ultra-Tech'' has various portable force screen generators while ''High-Tech'' provides explosives blankets which SWAT officers can use backward to protect themselves from attack.
* In ''TabletopGame/TheLordOfTheRingsStrategyBattleGame'', Corsair Arbalesters carry around big wooden pavises.
* The ''TabletopGame/{{Warhammer}}'' Siege Rules allow archer units to carry pavises.
** The newest edition's common magic item list includes 'Fozzick's Folding Fortress,' which allows you to put up an entire watchtower in your deployment zone.
* ''TabletopGame/DungeonsAndDragons'' has rules that allow a tower shield to be planted, meaning the user sacrifices all actions and the shield's usual bonus to AC and takes full cover (untargetable, although enemies can certainly aim for the shield) instead.

[[folder:VideoGames]]
* Players carrying riot shields in various shooter games become this for their teammates.
* This piece of equipment in ''VideoGame/{{Halo 3}}'' is the TropeNamer. You just tossed it out and it would throw up a shield that you could shoot through while blocking your enemies' shots.
** It also had the ''Bubble Shield'', a form of deployable cover that created a [[BeehiveBarrier sphere of protection]] 4m in diameter to wherever it was tossed. It could be walked through, but anything thrown or fired at it was unable to penetrate, even your own shots. Halo Reach included it as an armor ability, also making it smaller.
* GlobalAgenda features this in standard and LimitBreak formats for the Robotics class.
* The Block ability in ''S4League''.
* The Geth in ''Franchise/MassEffect'' seem to be fond of deploying hexagonal energy shields in areas with little cover.
** The Collectors in Mass Effect 2 also deploy shields, circular but still with a [[BeehiveBarrier glowing hexagonal pattern]] in them.
** Similarly, [[spoiler: In the collector base mission, one of your party must create a Biotic shield to repel seekers and maintain it during the fight.]]
** Cerberus in ''VideoGame/MassEffect3'' deploys similiar shields, though they can be easily disabled by shooting the generator.
*** In Multiplayer, the Geth Prime character class eventually brought back the energy shields from the first game, which is especially useful given that the Prime is one of the biggest playable characters and incapable of crouching behind cover.
* ''VideoGame/DragonAgeInquisition'' introduces a new [[AnIcePerson wall-of-ice spell]] that allows you to protect yourself and divide enemies.
* In ''VideoGame/{{Borderlands}}'', the Soldier's turret features an energy shield, as well as [[CaptainObvious shooting things]].
** Borderlands2 has the Commando with a similiar turret, which can also create a shield with the right talent.
* Girders in ''VideoGame/{{Worms}}'' can be deployed absolutely anywhere on the map and sort of magically spring into existence, and can be used for a certain degree of cover wherever it is needed.
* In at least the third ''RatchetAndClank'' game you can buy deployable cover.
* GI units in ''CommandAndConquer Red Alert 2'' can deploy sandbags which gives them increased resistance and also allows them to use their machine guns, but makes them immobile. The Guardian GI in the expansion can do the same, but using metal plates instead which makes them impervious from getting roadkilled by vehicles. How they get sandbags and metal plates is [[HyperspaceArsenal anybody's guess]], and worse, how they set them up in less than a second. GDI riflemen in C&C 3 can build foxholes, which are basically GarrisonableStructures though this cost some cash and takes a while to build, and if you leave them empty, the enemy can use them too.
* The Locusts in ''GearsOfWar'' have bombs that make pillars of earth shoot up from the ground, which they then use as cover.
** Gears of War 2 introduces a [[LuckilyMyShieldWillProtectMe shield]] that can be made into this.
** ''Gears of War 3'' will have Silverbacks, mech suits that can turn their legs into cover at the cost of not being able to move while they do it.
* Eldar guardians in ''DawnOfWar 2'' may deploy energy shields.
* ''VideoGame/{{Unreal}}'' featured a forcefield item that could be activated to seal off a doorway or provide cover in a gunfight.
* The gameplay of ''VideoGame/{{Fracture}}'' was built around the Entrencher, a device which in theory could raise and lower the ground to create cover and foxholes as needed. It didn't work well enough to make up for otherwise bland gameplay and story writing.
* [[StarCraft Zerg]] [[SquishyWizard Defiler]] can cast a spell that creates a cover, rendering all direct ranged attacks useless against units under it, including your own.
** ''VideoGame/StarcraftII'' ups the ante with sentries, the premiere defensive units of the Protoss. Their standard defense, the force field can be used to prevent melee units from getting up close and to keep ranged units out of attack range when you pair them up with Colossi. Their secondary defense the guardian shield reduces incoming damage to great effect since it does so over a wide area.
* Engineers in {{Stronghold}} are capable to create cheap and expandable shields that can be deployed in the battlefield to protect other units from enemy fire.
* The Auger's secondary fire in the ''VideoGame/{{Resistance}}'' series places a short-lived, man-sized wall of energy in front of the user, which is impervious to everything except Auger shots.
* Every ''VideoGame/{{Homeworld}}'' game has something that's supposed to work this way. The original game's Defence Field Frigates were an out-and-out [[UselessUsefulSpell Useless Useful Ship]][[note]]The defence field effect only really protected the ship itself, which could be worked around except for the fact that the game averts 2DSpace and the AI is bright enough to exploit this fact. Worse yet, two of the four kinds of attack in the whole game flat-out ignore the shield.[[/note]]. ''Cataclysm'' introduced Sentinel fighters that worked a bit like the Planet Defensors referenced in the ''Gundam Wing'' entry on a smaller scale, and were slightly more useful. ''Homeworld 2'' introduced a new Defence Field Frigate that corrected most of the original's deficiencies, but had a short duration and a long cooldown period.
* The Instant Wall in ''VideoGame/{{Amorphous}}''. It protects you from most Glooples except Grinders (but it breaks their shell), [[BossInMookClothing Void Eaters]], and a few others.
[[/folder]]

[[folder:WesternAnimation]]
* ''TheHerculoids''.
** Episode "The Time Creatures". The title opponents could press a button on their helmets and create a force field barrier in front of them.
** Episode "Invasion of the Electroid Men''. The title creatures could create an energy wall as a movable barrier.
* ''SpaceGhost'' episode "The Looters". Brak's ray shelter can generate an Impregnashield (a rectangular force field) in front of it.

[[folder:RealLife]]
* The Pavise was a shield designed to protect archers and crossbowmen from incoming projectiles, they often had a spike in the bottom, allowing it to be put in place, thus protecting the owner without them having to hold it.
* The Mantlet was a movable barrier that would protect from arrows, that could be put into position by the soldiers using it.
* Shell holes are often used as cover. In a variation of this trope, troops have at rare times requested artillery fire just to create them.
** In [[UsefulNotes/WorldWarOne 1915-1917]], (Allied) armies experimented with the use of a "creeping barrage" tactic, where the artillery would continually lay down fire just ahead of the advancing troops, using the shell blasts themselves as a form of cover. Creeping barrages soon became obsolete when the Germans realised (as a result of trying to conserve their increasingly scarce ammunition) that short, concentrated, and intense barrages on short sections of the enemy lines followed by lightening-fast assaults and break-throughs[[note]] the rest of the force following through these bridgeheads to encircle and force the surrender of/exterminate the forward sections of the enemy line[[/note]] were much more effective than either creeping barrages or the massive (week-)long barrages (followed up methodically but painfully slowly across a broad front) that had proceeded them both. 'Creeping Barrages' and 'Massive Barrages' were just too slow to result in anything more than tactical advances, as the enemy would always have enough time to bring up reserves to strengthen their lines, something that brief barrages followed by rapid assaults and breakthroughs managed to avoid (In theory, anyway. In practice, Germany's logistics capabilities were always too weak to properly sustain strategic offensives).
*** It's worth noting that 10% casualties were expected in a tactical advance covered by a properly-executed creeping barrage; most of those casualties were not due to enemy action[[note]] as one's own troops would be in excellent positions to force the enemy's to surrender by the score or be massacred in their dugouts[[/note]] but rather due to defective shells and mis-aimed artillery pieces resulting in some of the barrage hitting one's own troops.
* [[http://www.boingboing.net/2010/02/01/the-secrets-of-octop.html the veined octopus]] sometimes carries coconut halves around to use as portable armor. When it sees a predator it reassembles the coconut halves into a ball with itself protected inside.
* When dismounted, troops can use friendly vehicles, such as [[AwesomePersonnelCarrier Infantry Fighting Vehicles]] and [[TankGoodness tanks]] as cover during gunfights. This way they can have some protection from the small arms fire that likely makes up the majority of any fight, and are better able to pick off [[GlassCannon anyone carrying an anti-tank weapon]]. [[DontTryThisAtHome If you ever choose to use this technique]], remember that the [[TelevisionIsTryingToKillUs vast majority of motor vehicles]] [[ConcealmentEqualsCover are not actually bulletproof]].
** Be wary of being near vehicles with reactive armor, as it explodes into clouds of sharp, hot, toxic shards when struck by some forms of anti-vehicle weaponry.
* There are actually foldable kevlar-sheets that can be carried around like a suitcase (it intentionally resembles one) and quickly folded out to give some level of protection agains pistol caliber weapons. They fit here since they arenīt that mobile and the user has to manually hold them up with one hand while returning fire with the other.
* Sandbags! Load them on a truck, take them with you, and in five minutes team of two can construct cover for themselves. If you can't take a truck with you, you're out of luck, though, damn things are heavy.
** Unless you empty them out first and find your own dirt later...
