Which item is generally NOT included in weapon cleaning equipment?

In the context of weapon cleaning equipment, a digital thermometer is typically not included. The purpose of weapon cleaning equipment is to maintain and care for firearms, ensuring they operate efficiently and safely. Gun oil is essential for lubricating parts to prevent rust and ensure smooth operation. Patches are used to clean the interior of the barrel and other components, effectively removing fouling and residue. Brass, often in the form of cleaning rods or brushes, helps in the physical cleaning process.

A digital thermometer, however, does not have a direct role in the actual cleaning or maintenance of a weapon. It is more associated with monitoring temperatures for specific processes or environments rather than being an integral part of the cleaning tools necessary for firearm care. Thus, the exclusion of a digital thermometer from standard cleaning equipment is consistent with its lack of relevance in that specific task.
