Moving an Assault soldier with Lightning Reflexes to neutralize an enemy's Overwatch can allow the rest of your units to move with impunity; it also permits an Assault to break Suppression by moving without being hit by reaction fire. This can be especially critical on the higher game difficulties where any shot can prove lethal or on Council Missions where enemies (particularly Thin Men) tend to drop into the map and immediately go on Overwatch. While friendly suppressive fire can also disable an enemy's Overwatch, Lightning Reflexes has the advantages of not ending a soldier's turn or using ammo.
