Area fire ×½ counts attack-wide halvings (concealed target, spraying fire, …). Cowering is derived: leader direction or exemption → none; inexperienced → double; else regular.

Target (optional)
Personnel: break / pin / casualty odds via a second 2d6 morale check. Vehicle: kill odds from the IFT ★ line. Blank SAN skips the sniper calc.
Cowering shifts the column left on doubles. Off the 1-FP edge → no effect.
