High School of the Dead
The world is overtaken with a very deadly disease that turns humans into zombies. In Japan, several students of Fujimi High School, and the school nurse, band together to survive the present apocalypse. The story follows Takashi Komuro, one of the students who survived in the initial outbreak.
The following weapons were used in the anime High School of the Dead:
Smith & Wesson Model 37
Takashi Komuro and Rei Miyamoto find two Smith & Wesson Model 37s on a pair of dead police officers, though one has its handle broken (though the broken one is not seen on screen). Takashi comments on the gun having only five shots as most revolvers usually have six, and while inexperienced with firearms, knows to keep his finger off the trigger when not intending to shoot. Takashi later hands the revolver to Kohta due to the latter's expertise with firearms. Several police officers are seen firing their M37s at zombies trying to breach their roadblocks and a senior officer executes a anarchist inciting a unruly mob on live television before the officer later commits suicide with his sidearm near other officers. The author commented on how the Nambu Model 60 was no longer the official sidearm for all Japanese police officers and therefore chose the Smith & Wesson to show the unique choice of weapon for each department. This is correct since the NPA imported Model 37s from America to outfit officers who are going to be armed with revolvers.
SIG Sauer P226R
In Episode 8; "The Dead Way Home", a Secret Service agent uses SIG P226Rs to gun down zombies trying to reach the wounded President and Chairman of the Joint Chiefs alongside a few remaining staff members on board Air Force One. Another staff member armed with a P226R uses it to shoot the wounded Chairman in the head upon the latter's request after he shows signs of zombification. Rika Minami uses a P226R fitted with a scope mount, small red dot sight, and flashlight as her sidearm, however because the battle at the offshore airport didn't happen on-screen in the anime, it's only seen in the opening sequence and in her leg holster.
Saya Takagi's mother, Yuriko Takagi, hands her daughter a Navy model Luger P08 complete with a 32 round "snail" drum magazine and a stock. It is referred to as "Luger P08's Holland colonial military model". It is most likely a artillery model of P08, since it has a long barrel and a drum magazine. But it could be based off of the Luger P04 Navy model, because the sights are raised and appear to be adjustable but are on the rear of the frame, this is a feature found only on the P04. The P08 artillery (the only other luger with an elongated barre)l has it's adjustable rear sight on the barrel.
A Right Wing member (or Nationalist) is seen firing a M1911A1 at the approaching zombie horde in the final battle at the Takagi estate with the zombies.
Yuriko's Browning M1910 is seen in the opening sequence, and it is seen in the show proper in her leg holster.
Yakuza members and several civilians are seen running amok with Remington 870s. A flashback reveals that Kohta trained with one while on vacation in the U.S. undergoing a firearm's training course.
Remington 870 Field Shotgun
Another Yakuza gang member is seen using a Remington 870 Field Shotgun with the barrel (presumably) cut down for easier handling.
An Ithaca 37 is found in Rika's household, in a firearms locker which Takashi and Kohta break into. Kohta initially uses it before handing it to Takashi, who uses it as his main weapon for the rest of the show. Kohta instructs Takashi on how to slamfire the M37 (holding the trigger down and pumping the shotgun, causing it to fire as soon as it's back in battery) when the group is cornered at the wire blockade, and Saya uses the dropped M37 later in the same scene. Takashi later uses it a melee weapon after running away from the wire blockade. The M37 is fitted with an Aimpoint CompM2, which is later disabled by the EMP due to it being powered by a 3-Volt Lithium Battery.
Over and Under Shotgun
A citizen is seen firing an over and under shotgun, but fumbles in loading the shells and is promptly surrounded and devoured by zombies.
A Remington Model 1100 is seen during the final episode being used by a Nationalist member.
Heckler & Koch MP5A4
Riot Police (機動隊 Kidotai) officers are seen firing Heckler & Koch MP5A4s at zombies.
Skorpion vz. 83
Yuriko is seen fighting zombies with a Skorpion vz.83 as her primary weapon. She only uses it set to semi-auto, a wise decision considering the number of zombies, and that a headshot is required to kill them.
Springfield Super Match M1A
A Springfield Super Match M1A is found in Rika's household, and is used by Rei as her main weapon. It has an OD stock and is fitted with a standard M14 flash hider (which has a bayonet mount), M14 DMR cheek riser, KAC rail system, custom-fitted lower rail, KAC QD sling mount, Surefire M900V foregrip/light combo, Aimpoint CompM2 red dot sight with a killflash, its magazines are fitted with Magpuls, and the rifle is later fitted with an M6 bayonet to complement Rei's fighting style. As with the CompM2 on the M37, this one is also later disabled by the EMP. In episode 7, Takashi handles the rifle to shoot at zombies about to eat Rei. Kohta, like in the Manga, incorrectly calls it an M1A1 with the extra number 1.
An Armalite AR-10(T) modified to resemble a Knight's Armament SR-25 is found in Rika's household, and due to the aftermarket parts Kohta initially mistakes for the latter rifle. It is fitted with a Knight's Armament rail system and rail covers, Leupold M3A scope with a sunshade, and a bipod; Kohta uses it as his primary weapon. The author comments Rika seduced an American soldier to import the illegal rifle into Japan via the American military air service, avoiding customs. An error in the English dubbing caused Kohta to misidentify it as an "AR-110" instead of an AR-10.
Howa Type 89
JGSDF soldiers are seen wielding Howa Type 89s as their service rifle, an well as one being used by Kohta in his imaginary FPS. Rika's personal rifle is a highly customized Type 89 with an entire M4A1 front end, including the barrel, front sight, and rail system, as well as an M4A1 LE stock, and is fitted with an Aimpoint CompM2 and Surefire M900 foregrip/light. However, due to the airport battle, where she used this as her primary, not appearing on-screen in the anime, it's only seen in the opening credits.
Members of the Right Wing (or Nationalist) group are seen firing M16A1s at the approaching zombie horde during the final battle at the Takagi Estate in the final episode.
If you look at the left, you can see three different rifles, where there's a AK variant, AR variant (I think?) and a Steyr AUG.
Heckler & Koch PSG-1
Rika uses a Heckler & Koch PSG-1 fitted with a Harris bipod in her role as a Special Assault Team sniper, clearing an airport of zombies wandering around its runways. Very notable is that she correctly fires the full load of six rounds in this scene; proper magazine capacities are usually the first thing ignored in fiction, however attention to detail in this regard is seen throughout the show.
A Sumitomo Minimi, the Japanese-licensed version of the FN Minimi, is seen mounted on a JGSDF Type 82 reconnaissance vehicle.
Sumitomo Type 74
A Type 74 is mounted on a JGSDF Type 10 MBT as its coaxial machine gun.
A Sumitomo M2, the Japanese-licensed version of the Browning M2, is seen mounted on a JGSDF Type 10 MBT.
