With the recent Henry Cavill Commando movie in mind, in which assorted STEN MK IIS got a lot of screen time, I thought this recently released Squire video was humorous and hit a “my thoughts exactly” when comparing the STEN Mk IIS against the famed Fairbairn-Sykes fighting knife in use by Commando types in 1943-45.
The integrally suppressed MK IIS was a thing to behold.

The screen-used STENs in the Ministry of Ungentlemanly Warfare have a much larger can installed
For reference on just how quiet an MK IIS could get, from my personal experience is a kit gun built by SilencerCo that I fired when on a tour there. It is just a baby poop green weld-up from a surplus parts kit with what I feel like was an Omega 36M multi-caliber can on it.
While likely not as quiet as an integrally suppressed MK IIS, it is still almost Hollywood.
