During a discussion with my boyfriend, he suggested that a scene in 'Band of Brothers' was factually incorrect because American genreal-issue rifles could not be disassembled to be cleaned. He reasoned that the springs in the firing mechanism were so precisely aligned and disassembling would ruin this alignment, thus meaning the gun couldn't be fired again.
Me, being the sceptic that I am, tried to research this online but came up with a lack of information supporting my gut feeling that guns were able to be disassembled. So I came to reddit!
So, r/AskHistorians, is this true? Could American general-issue rifles be disassembled to be cleaned? Or is my boyfriend right? References would be highly appreciated.
Thanks, Girl who refuses to take anything at face value
You are correct, the weapons issued to US soldiers in the second world war could all be disassembled by the men who carried them. If he lacked the ability to fix malfunctions and swap out damaged parts as the weapon went through the rigors of combat, mud, and dirty ammunition a soldier would quickly find himself the owner of a 10 lb bludgeon.
Soldiers were advised to only perform certain procedures under the supervision of armorers, such as disassembling the iron sights or mucking about with the gas system, but were by no means physically unable to do so. The small size and delicacy of the parts involved meant that doing so when unnecessary was not advisable.
Below are field manuals issued to American soldiers detailing the proper maintenance and disassembly of some of the main firearms they carried.
It's called field stripping and is a critical part of field maintenance of a weapon.
Basically, you break a gun down to it's major assemblies (bolt, gas system, bolt carrier, or other bits depending on the weapon ). You clean dirt and fouling, lubricate it, and reassemble. A hallmark of a well designed military weapon is it's ease of field stripping and maintenance.
Beyond field stripping is detail or armory level stripping, where a weapon is torn down to all it's components. Soldiers are generally not trained or authorized to conduct that level of work, due to the complexity and numerous small bits. Plus it's only needed for major repair, rebuild or overhaul. So your boyfriend was kinda right, you aren't going to detail strip a rifle in the field, but if you value your life and a functioning weapon, you damn well better field strip and maintain it.
