"Equipment" defines a long list of objects that cannot be "used up" like ammunition or healing supplies can. While these items may not be absolutely necessary to complete a mission, they do make things much easier. The "Equipment" section is broken down thusly:

Firearm Accessories - This area lists all the different types of accessories that can be added to the Firearms in the system. From scopes to lasers and everything else, it's all included here.

Outfit Attachments - Outfit Attachments include all manner of things that can be worn over the clothes. Things like Tactical Thigh Rigs or Load Bearing Vests can be extremely useful as they can carry things like weapons, ammunition, healing supplies and other commonly-needed items without having to place them in Item Spaces. Gear properly chosen, Item Spaces might only be needed to store really important stuff, like keys.

Armour - Not just Body Armour, but things like helmets and shields, can be used to minimize damage. With enough armour, many enemies may present little more than an annoyance. Part 14: Armour in the Survival Manual explains this further.

Tools - A tool is anything needed to accomplish a task. In CYStH, this diverse category includes things people normally associate with the word "Tool" such as wrenches and screwdrivers, but also includes things like Flashlights, Torches and more.

Innate Items - Nearly every Training Discipline offers an Innate Item to further enhance the functionality of people trained in that Discipline. Innate Items are kits of tools and other things that can never be used up, and are never placed in an Item Space. They can carry tools and supplies within them, and can sometimes even be added to.
