The '''shotgun guy''', also called the '''former human sergeant''' in the game manuals, and sometimes shortened to '''sergeant''', is an armored space marine which has been turned into a [[Former human|zombie]] during the invasion from [[Hell]]. The [[monster]] appears as a red-eyed bald man wearing bloodstained slate-gray body armor and clothing, and wields a [[shotgun]]. Angrier in appearance than the lowly [[zombieman]], and around three times as powerful, a shotgun guy can challenge the most hardened of Doom veterans. His official description reads:

{{Quote|Same as the Former Humans, but much meaner, and tougher. These walking shotguns provide you with a few extra holes if you're not careful!|Doom instruction manual|Doom instruction manual}}

==Combat characteristics==
[[File:sgtnojoi.png|thumb|Shotgun guys loitering in {{Idgames|file=levels/doom/deathmatch/j-l/joi-cm1|title=JOI-CM1.WAD|linkonly=1}}]]
This type of zombie is armed with a shotgun, which is less powerful than [[Shotgun|the player's shotgun]]: one round produces only three pellets instead of seven, and each pellet inflicts slightly less damage on average. When the shotgun guy attacks, it aims its shotgun at the player for about 3/10 of a second and fires a single round. Each pellet has the same dispersal as a trooper's bullet (standard deviation around 9°, to a maximum of ±22°); this is calculated independently for each pellet, so multiple hits are occasionally scored even at very long range. After firing, the monster [[Monster behavior|moves again]].

When killed, the shotgun guy drops its weapon, which contains 4 [[Shotgun shells|shells]] (or 8 on [[I'm too young to die]] and [[Nightmare!]]). If it subsequently [[Skill level|respawns]] or is [[Arch-vile|resurrected]], the shotgun remains. The shotgun guy's chest and its abdomen spill blood as it is felled, assuming it is not [[gibs|gibbed]], which is not uncommon, considering its relatively low number of [[hit point]]s.

==Tactical analysis==
Due to the dispersal of the pellets from its shotgun, the shotgun guy is only a marginally greater threat than the [[zombieman]] at long range. However, at closer ranges its shotgun blast can damage the player significantly, and many stock levels create ambushes by placing sergeants on ledges and around corners.

The player's shotgun generally kills individual shotgun guys at medium and long ranges, and can occasionally kill two or more with one shot at close range. All other weapons are effective against shotgun guys, although the [[pistol]] leaves it ample time to retaliate, and the [[fist]] and [[chainsaw]] are dangerous to use because the player risks being shot at point-blank range. This can be fatal if the player does not have any form of [[Armors|armor]] available.

The shotgun guy's contribution to [[Monster infighting|monster-monster battles]] is average at best. It is more durable than a zombieman, and can damage more than one creature per shot. However, it fires much less frequently than a player would, and circles its target in an irregular pattern which prevents it from attacking at close range every time. Thus it can be defeated by a healthy [[imp]] more often than not, and most often by a [[demon]].

Very large groups of shotgun guys may suffer significant losses from infighting (as with the [[red key]] area in the user made {{Idgames|file=levels/doom/s-u/urmeat|title=URMEAT.WAD|linkonly=1}}) simply because of the sheer number of pellets being fired. If shotgun guys are encountered in groups, they are usually positioned in formation to minimize infighting from the pellet spread.

Shotgun guys may also be used in turret or alcove situations, usually placed a considerable distance from the player to minimize damage from a [[chaingun]] or [[super shotgun]]. It may be best to switch to the shotgun to take out these monsters, due to its narrow spread.

Certain stock maps (especially those of [[Knee-Deep in the Dead]]) include a large number of additional shotgun guys on [[Ultra-Violence]] as compared with the lower skill levels. While increasing difficulty overall, their dropped shotguns also greatly increase the number of shells available to the player.

In the Nightmare! skill level or under the influence of the {{c|-fast}} [[command line parameter]], the shotgun guy's attack rate increases so significantly that they can make some stock maps in Knee-Deep in the Dead nearly impossible. Notable examples include the starting walkways in [[E1M3: Toxin Refinery (Doom)|E1M3: Toxin Refinery]], and the central hub of [[E1M9: Military Base (Doom)|E1M9: Military Base]].

==Inspiration and development==

==Notes==
* Despite being called a "sergeant" in the manuals, the shotgun guy has the type name {{c|MT_SHOTGUY}} in the [[Doom source code]], and the [[sprite]] prefix {{c|SPOS}}, while the analogous {{c|MT_SERGEANT}} and {{c|SARG}} are given to the [[demon]]. This is likely because the demon was initially named "demon sergeant" in the [[Doom Bible]] (section 7.2).
* Depending on the skill level chosen, the shotgun guy may be the first monster seen to new Doom players. A considerable number of them populate [[E1M1: Hangar]] when it is played on Ultra-Violence or higher.
* The official French name of the monster is ''type au fusil''.

#This table assumes that all calls to [[Pseudorandom number generator|P_Random]] for damage, [[pain chance]], [[blood]] splats, and bullet dispersal are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as [[Sector#Doom|flickering lights]]). Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
#The target must be close enough to compensate for the monster's inaccurate aim.

==Other games==
===Doom 64===
{{Main|Doom 64 monsters#Former human sergeant}}

The shotgun guy makes an appearance in [[Doom 64]], and is the most common type of zombie in the game. However, it uses the same sprite as the [[Zombieman]], but with a different [[palette]] applied which changes the color of his pants. This makes the two monsters almost impossible to differentiate in the game's darkness. They first appear in [[MAP01: Staging Area (Doom 64)|MAP01: Staging Area]].

===Doom 3===
{{Main|Z-Sec}}

In [[Doom 3]] and its expansions, armed zombies called Z-Secs occur in a wide variety of forms, one of which is helmeted with black armor and empty eye sockets, and wields a powerful shotgun which can throw the player back and do a dangerous amount of damage. They are neither as common nor as intelligent as the more dangerous [[machine gun]]-wielding Z-Sec, however, almost never employing cover tactics due to the short-range nature of their attack.
