->''"Look, we know you're new to this command, but the army field manual is very clear on the subject of squad stereotype composition. Every squad must include: 1 quiet religious guy who goes insane, 1 maverick loose cannon who plays by his own rules and dies in a blaze of glory, 1 covert recon operative with a dark past who at first betrays the team but then has a last minute crisis of conscience and nobly sacrifices himself for the greater good, 1 fresh faced new recruit who survives but loses his innocence and learns to become a man and 3 or 4 other guys who you don't care about so they can get brutally shot so you can show how serious the war is."''

Military and war stories have a number of different levels of focus, from the global strategic level all the way down to squad tactics, and even the plights of individual soldiers on the battleground.

When the focus is at the smaller end of the scale, we get this trope. Very often, this is a squad composed (like a FiveManBand or TheTeam) of interlocking character types or roles.

There are quite a few similarities with the types and roles of the CommandRoster. The main difference is the CommandRoster is a very specific combination of skills that may not be [[MildlyMilitary strictly military]]. The Squad may be a BadassCrew and have a SquadNickname. If it's made up of women, it's an example of an AmazonBrigade.

The trope's inspiration comes from the [[http://en.wikipedia.org/wiki/Fireteam fireteam]] and [[http://en.wikipedia.org/wiki/Squad squad]] units of infantrymen. Such a setup possibly first appeared in UsefulNotes/TheNapoleonicWars, where open order skirmishers armed with rifles (at the time, more accurate but slower to reload than standard muskets) depended on close coordination to be effective. They would stealthily get into a good position to fire good shots and avoid the sweeping, densely-formed gunfire that enemy line infantry units provided. The use of [[https://en.wikipedia.org/wiki/Fire_and_Movement fire and movement]] tactics - some soldiers move towards the enemy, others provide covering fire - also contributed to the reorganisation of militaries into small squads. However, gunpowder in UsefulNotes/TheNapoleonicWars was "black powder" that would quickly fill a battlefield with thick smoke, which made firing accurately difficult. [[TropeCodifier It was not until]] UsefulNotes/WorldWar1, where breech-loading rifles using smokeless powder had become commonplace, that the average infantryman became far more accurate and quick-firing. Throwing in the proliferation of machine gun crews that would inevitably shoot first when a mass of men approached them, defenders in cover were granted a huge advantage. Military science thus experimented: infantrymen would attack fortified positions in small groups, approaching with methodical covertness. This became the default method of military tactics, and remains so to this day.

Some of those character types and roles:
* TheLeader, who might be of several different types. If the leader is an OfficerAndAGentleman, expect a CaptainSmoothAndSergeantRough relation with a SergeantRock.
** ColonelBadass or MajorlyAwesome
** TheNeidermeyer
** EnsignNewbie, in which case there will ''always'' be a SergeantRock present
* The shooter, often a
** ColdSniper
** FriendlySniper
* One or more [[UtilityPartyMember technical]] [[TheSmartGuy "Smart Guy"]] who can take any or [[OmnidisciplinaryScientist all]] of the following roles:
** TheStrategist
** TheEngineer
** CommunicationsOfficer
** CunningLinguist
** [[HollywoodHacking The Hacker]]
** VoiceWithAnInternetConnection
* TheMedic (sometimes another SmartGuy variant), sometimes as a CombatMedic
* A charismatic smooth talker
** TheSocialExpert
** TheFace
* TheBigGuy
** DemolitionsExpert
* [[DesignatedPointMan The Point Man]]
** TheSneakyGuy
** ArmyScout
* The Veteran
* NewMeat
* TheQuietOne
* SadClown
* SouthernFriedPrivate
* TheSquadette
* TokenAdult

If the story follows the characters through boot camp, or specialized training, expect to see DrillSergeantNasty make an appearance. If the story follows them after the war, expect at least one ShellShockedVeteran.
