Blood & Guts 2.0: Battlefield Unit Combat System

However, what does the GM do when a combat situation involves hundreds of people? There are a number of strategies that wily GMs have adopted over the years to handle this, usually involving just a tight focus on the PCs and their actions during a larger battle.
