S2. Work out Blast markers

When your units shoot at a target detachment, that detachment will tend to accrue Blast markers. Blast markers represent the chaos and confusion that a target detachment suffers when it comes under heavy fire.

The number of Blast markers that you place on the target detachment depends upon the total Firepower that you direct at it, before modification (for Assault orders, Blast markers on the detachment, and so on).
