Ear notch

The term ear notch, a calque of the Commonthroat word HKrqFdqg /long rising strong growl, chuff; huff, late high weakening whine; huff, short low weak growl/ is used as a derogatory term for a firearms enthusiast in an analogous manner to the English term gun nut.

Older yinrih firearms are worn on a saddle mounted on the back, and are fired using a remote trigger wired to the gun assembly and held in the tail or paw. Depending on the length of the gun barrel, it's possible for the user to accidentally lose a chunk from an ear if they don't assume a proper firing posture, hence the nickname "ear notch".

Modern firearms are incorporated into remotely operated drone capsules such as those used as part of most powered armor, and these don't carry the same risk as older back-mounted firearms.
