Firing when in enemy melee range (directly adjacent to any enemy) is governed by different rules than ranged shots. A special Close Combat Check is rolled, using 1/2 Melee + 1/2 Reactions, times weapon's CQ Accuracy modifier (average 85%). Evasion (if any) of the enemy closest to gal's front is subtracted from that value. Note that this check is performed always, regardless if you're targeting the enemy in melee range, or anything else.
