What are the three special tools included in the toolkit for servicing the Cutter Assembly Mk 12 Mod 2?

The three special tools included in the toolkit for servicing the Cutter Assembly Mk 12 Mod 2 are indeed the Breech Removing tool, Cartridge Extractor Tool, and Drift for Punch Shear Pin. These tools are specifically designed for the unique requirements of servicing the Cutter Assembly, allowing technicians to perform their tasks effectively and efficiently.

The Breech Removing tool facilitates the removal of the breech component, which is essential for accessing the internal mechanisms that may require maintenance or adjustment. The Cartridge Extractor Tool is engineered to safely and effectively extract spent cartridges, an important function for the operation of the assembly. Lastly, the Drift for Punch Shear Pin is critical for installing or removing shear pins that may hold various components together within the assembly.

In contrast, general tools like a wrench set or screwdrivers, while useful in many applications, do not directly address the specific tasks associated with the Cutter Assembly Mk 12 Mod 2. Hammers and chisels, although they have industrial uses, are not specialized for the maintenance and repair of this particular equipment. Therefore, the correct answer highlights the specialized nature of the tools required for the Cutter Assembly's servicing procedures.
