Normally I would post a specific question but other than the feeling that something is very off with my best interpretation of Interstellar Operations Abstract Combat System Combat rules on pages 316 to 317 I can't quite place where things are going wrong. So below I have posted my best by-the-book guess at how a formation on formation attack is conducted. If you could point out how an attack should actually be made and where this example derails I would greatly appreciate it.
Example: Resolving the attacks of Formation A (CUs A1,A2,A3) vs Formation B (CUs B1,B2,B2). Formation B has TMMs as follows:
Formation B:
CU B1: TMM2
CU B2: TMM5
CU B3: TMM5
Attack Declaration: Formation A declares an attack against Formation B.
Combat Tactics: Formation A chooses Standard Tactics.
Resolving Attacks:
Determine Range: It is determined that Formation A engages Formation B at medium range.
Determine TO-HIT Number: Each CU in Formation A targets CU B1 with its TMM of 2 to get the best TO-HIT number.
Roll TO-HIT CUs A1 and A2 succeed while A4 fails their TO-HIT rolls against B1.
Determine and Apply Damage:
Determining Damage: Per the rules of Standard Tactics(pg. 316) both A1 and A2 deal full damage and A3, who failed his TO-HIT roll, deals .8 damage. However, only successful TO-HIT rolls are applied so A3's .8 damage is left unapplied and discarded.
Applying Damage: Per SBF rules for Applying Damage (pg. 240) a Tactics Roll is made. Formation A wins the roll and decides to Apply both both A1 and A2's successful attacks to B3. Formation A chose B3 so that it will have B1 with its TMM of 2 to target in subsequent rounds for better TO-HIT numbers.
