Some weapons are universally loved by the troops that carry them. Others somehow make it past the drawing board, through testing, and into the hands of soldiers — who then hate them. These are the most reviled.
6. The Ross Rifle
The Ross Rifle was a Canadian rifle with some interesting design features that saw service in WWI. For one, it had a single-motion bolt that was supposed to make it quicker to fire than the turn-and-pull style of conventional rifles. However, this feature also allowed for the rifle to be reassembled incorrectly and still fire, which resulted in the bolt flying out the back and killing or maiming the shooter.
"Everyone line up for a rifle and an apology."
Also, despite excellent accuracy in range conditions, the rifle proved very susceptible to jamming when caked with the dirt and mud of combat. Additionally, the bayonet of the Ross also had a tendency to fall off when the weapon was fired. The performance of the rifle was so poor that many Canadian soldiers discarded them in favor of Lee-Enfields they took from dead British soldiers.
5. Breda 30
The Breda 30 was an Italian light machine gun used in WWII. Italian designers were having trouble with round extraction and arrived at a solution that arguably made things worse. The gun had a system that lubricated each cartridge as it entered the chamber with the idea that it would make extraction easier. In reality, the oil attracted dust and dirt, which fouled the action and slowed the gun's rate of fire. Despite the slowed rate of fire, the barrel would still heat up, which would inevitably heat up the oil and, in turn, cook off a round in the chamber.
Which was terrible if you were firing while riding a motorcycle.
If that wasn't a poor enough design, the gun also had a fixed, 20-round box magazine that had to be loaded with stripper clips. To say the troops weren't fond of the Breda would be an understatement. The Breda was such a poor weapon, Italian troops often had battles turn against them because they could not keep up sufficient fire.
4. Sten gun
The Sten gun is one of those weapons that, despite serious drawbacks, was able to stay in service after much-needed improvements. Designed and built under the threat of a German invasion, the early models of the Sten, especially the Mk II's and Mk III's, were cheap and poorly made, earnings them nicknames, such as "Plumber's abortion" and "the Stench gun."
Still, it looks cool.
Sten guns were notoriously unreliable and had issues with misfires, even when simply set down. The issues were so pervasive that units would extensively test their Sten guns before combat in order to weed out the bad ones. Eventually, as improvements were made and quality improved, Mk V versions of the Sten would see combat with British paratroopers and other frontline units.
3. FP-45 Liberator
The FP-45 Liberator was a small gun meant to be distributed to guerrillas and resistance forces throughout Europe and Asia. The pistol, though firing a .45 caliber round, was only single-shot and required a wooden dowel to remove the spent cartridge. It also had an effective range of about 25 feet.
If any weapon was ever "adorable," this was it.
This was meant to have a great psychological effect on the enemy. However, the pistol never really got a chance to be hated by the troops as neither the generals in Europe or the Pacific saw the weapon as worth using. Large numbers of the pistols were passed on to the OSS, but they didn't find them worth giving out either.
Like the Sten gun, the M16 had a troubled beginning but, after improvements, later found affection from the troops who carried it. In its early days, in the jungles of Vietnam, the supposedly self-cleaning rifle failed in combat conditions. The major problem was a "failure to extract," or when the chamber became fouled due to excessive firing. U.S. troops, not issued sufficient cleaning kits, were often found killed with their rifles disassembled as they tried to clean them and remove the jammed cartridge in the middle of a firefight.
TFW your primary motivation for killing the enemy is to take his AK.
American troops hated the new rifle. However, the U.S. military quickly made changes to the rifle that increased its reliability. Despite early issues, it has gone on to be the longest-serving standard rifle in the U.S. military.
The Chauchat is perhaps the most-hated weapon on this list. Designed by the French to operate as a light machine gun carried by one man, it had numerous shortcomings. One major problem was its open-sided, half-moon magazine. The open side allowed mud and dirt to enter the magazine, impeding the ability to feed and causing stoppages. The long recoil operation of the gun also caused stoppages when it heated up and jammed the barrel to the rear.
The weapon was so unreliable that, in combat conditions, it frequently jammed after only 100 rounds. Unfortunately for the troops, there was no alternative for a light machine gun until the Americans brought the BAR into action near the end of the war.
