CBRN General Operations 74D Practice Exam 2026 – Complete Prep Guide

In the item order system, codes are structured so the letters group items into a category and the numbers identify the exact item within that category. For CS capsules, the catalog assigns a specific code with that category’s prefix and the exact item number. The code for CS capsules is K765. The nearby codes with the same prefix (K764 or K766) would refer to related items in the same category but not the CS capsules themselves, while a code with a different prefix (like C765) belongs to a different category entirely. So K765 uniquely identifies the CS capsules in the system.
