New GM, how to know how many enemies to place on the board

By William232, in Only War

I've flipped through the rules a couple of times now and havn't found anything to calculate the number of enemies you should bring to fight the Player characters. I've found a "TB" stat listed on the NPCs, but without a "TB" stat for the players, it is hard to create an encounter that would be both challenging but not be unfair to the player characters. Am i missing a part of the rules? How do yall calculate how many enemies to bring?

Firstly, "TB" is abbrevation of Toughness Bonus, this is for easier calculation for total AP (Armor points) + TB (Tougness Bonus) when reducing damage.

OW p.350 has the information about enemy challenge ratings and how many to include to make it a challenge for said squad.

Here's how adversaries are categorized in OW: Troops , Elites , Masters and Handlers & Minions
