Trivia

 * Many Pack-a-Punched weapon names are opposites of their unupgraded names (i.e. "Olympia" and "Hades").
 * "LSAT" and "FSIRT" are puns on the words "last" and "first".
 * "FN FAL" can be pronounced as "effin fail", while "EPC WN" is supposed to be pronounced as "epic win". "FAL" and "WN", the shorter weapon names in Call of Duty: Black Ops II, simply stand for "fail" and "win".
 * The "M72 LAW" and "M72 Anarchy" are a reference to anarchy being the opposite of law.
 * Some Pack-a-Punched weapons have numbers that stand for letters, a reference to "leet-speak", a symbolic alphabet that uses a combination of ASCII characters to stand for letters (5 = S, 3 = E, |-| = H, etc.).
 * ".357 Plus 1 K1L-u" is leet for ".357 plus I kill you".
 * "C-3000 b1atch35" is leet for "see 3000 biatches".
 * "F1W" in "F1W Nitrogen Cooled" is leet for "FTW", a common abbreviation for "for the win".

 * "SM1L3R" is leet for "smiler," which can be pronounced "similar".
 * Some of the Pack-a-Punched weapon names in Call of Duty: Black Ops II Zombies are backronyms of the weapon's original name (i.e. the RPD becomes the "Relativistic Punishment Device" and the MTAR becomes the "Malevolent Taxonomic Anodized Redeemer").
 * "Synthetic Dozen" stands for "Synthetic 12", a backronym of the unupgraded name "S12".
 * "1001 Samurais" is a reference to the weapon's Japanese origin (as Samurais are Japanese fighters) and the popular film "101 Dalmatians".
 * "M1000" and "M1 Garand" stand for 1000 = 1 Grand, which is how players often pronounce the weapon's name.

 * The "Infra-dead" in "Hyena Infra-dead" refers to the added Infrared Scope.
 * "V-R11 Lazarus" is a reference to Lazarus, a man believed to have come back from the dead. "V-R11" stands for the Vril, a fictional device with a similar effect. The game has multiple other references to the Vril.
 * Zeus, as in "ZeusCannon", is the ancient Greek god of sky.
 * "SPAZ-24" is a reference to its 24 round magazine. 24 is also 2 times 12, as in "SPAS-12", which could mean 2 times more powerful.
 * "Reznov's Revenge" is a reference to Viktor Reznov. The last weapon he used before his death was an AK-47. This could mean that this is the same AK-47 as in Mob of the Dead.
 * Some Pack-a-Punched weapons have the number 115 in their name, a reference to Ununpentium, also known as Element 115, which was related to the creation of the zombies, teleporters and the Wonder Weapons.
 * It can be said that on Call of Duty: Black Ops Wii, it seems that all the Pack-a-Punched weapons are green except the Porter's X2 Ray Gun which is black and orange, however this may just be a visual or texture glitch.
 * All Pack-a-Punched weapons have a certain Pack-a-Punch camouflage scheme. In Call of Duty: World at War, the camouflage is a metallic tone, while in Call of Duty: Black Ops, the camouflage is more of a machinery tone with what looks like circuitry covering it, and in Call of Duty: Black Ops II,  the camouflage is a swirling tone with a mix of red, green and shining metal covering each weapon, except in Mob of the Dead, where it is a rock camouflage with glowing magma lines coming through it.
 * Treyarch stated that the Arisaka will be able to be Pack-a-Punched in Der Riese. Since they referred to it as the Type 99 rifle, this has caused many players to believe that the Type 99 machine gun could be Pack-a-Punched.
 * Mustang and Sally is a reference to the song Mustang Sally. On the front of the game's box, the soldier is holding an M1911 that has the word "SALLY" and the number 8 in tally marks carved in the side.
 * "Typhoid and Mary" is an obvious reference to the actual person Typhoid Mary.
 * "Tokyo and Rose" are likely a reference to the actual people nicknamed Tokyo Rose.
 * "Calamity and Jane" likely a reference to the actual person Calamity Jane.
 * Just like the Ray Gun, the "Mustang and Sally" push the user back when fired.
 * The name of the Pack-a-Punched version of the Uzi, "Uncle Gal", is a reference to Major Uziel Gal, the designer of the Uzi.
 * Many Call of Duty: Black Ops guns including the AK47, Kiparis, Stoner63, Skorpion, WA2000, and a cancelled gun called the Sabertooth were once available in zombies mode with their own Pack-a-Punched versions, as according to the game files.
 * "The Widow Maker" is a somewhat common term for something that kills many men.
