• In the strategic and tactical bombing raid rules, it states that “all of the air units have attack and defense values of 1.”

    While I have been playing Axis and Allies 1940 Global 2nd Edition for a while, I only recently discovered the wealth of knowledge that is collectively possessed here so I need help solving an argument I have been having in my group. I am of the opinion that the above rule means that the attacking strategic bombers (and any escorting fighters, but that is not my real question) get a @1 chance to kill the intercepting fighters just as the intercepting fighters get an @1 chance to kill the strategic bombers.  However, several of my playing companions believe this only applies to the fighters getting a chance to kill the bombers and the bombers don’t get to shoot back.

    Needless to say, that can slightly change the calculus and sometimes dramatically change the results so which of us is right?  And, can you provide documentation or other source data to prove the answer?

    Thanks in advance!

    The bombers hit at 1 as well. Nice that you’re here Shadow.

    If your fellow players ever played a Spring 1942 game (1942.1), that was the OOB SBR rule.
    StB gets no attack while escorting Fgs get to roll @1.

    There was other variations from the actual OOB Global rule but it is not necessary to get into the other details.

    1- All attacking and defending planes roll @1.

    2- Then Tactical bombers and Strategic bombers must submit to IC’s AA gun @1 per each bomber.

    Latest OOB SBR rules for references and comparison:
    1942.1 : AA fires against Fgs and Bmbs, then surviving Fg A1 & Bmb A0  vs Fg D2
    1942.2 : Fg A1 & Bmb get A1 preemptives shots vs Fg D2, then AA fires against bombers only.
    Global 1940: Fg A1, Tc Bmb A1 or Strat Bmb A1 vs Fg D1, then AA fires against bombers, both types.

  • @Shadow7:

    …so which of us is right?  And, can you provide documentation or other source data to prove the answer?

    You are right, and you can easily convince your friends just by presenting them the rulebook:

    @rulebook:

    This air battle is resolved in
    the same way as a normal combat, with the following
    exceptions:

    • The attacking bombers and fighter escorts and the
      defending fighter interceptors will be the only units
      participating in this special combat.
    • The combat lasts for only one round.
    • All of the air units have attack and defense values of 1.

    Not only the third hyphen is relevant here, but the very first, too - here the units that are part of that battle are listed, including the attacking bombers.

  • Customizer

    I have seen 2 ways to conduct SBRs in Global 40.
    1 - Attacking bombers and fighter escorts roll @ 1. For each hit, a defending interceptor is placed in the casualty zone. Then all interceptors roll @ 1.

    2 - Attacking bombers and fighter escorts roll @ 1. For each hit, a defending interceptor is destroyed immediately. Then any surviving interceptors roll @ 2.

    So I guess it depends on which way you want to do it.

    The second method is based upon 1942.2 SBR rule.
    Did you play that way on Triple A? or only in F2F board game?

  • Customizer

    F2F board game. I haven’t played Triple A.

    I was wondering where I got the two different methods from. I thought one was possibly from one of the Alphas.
    When we play, we don’t worry about it until the first SBR that involves interceptors and escorts. Then I ask everyone which version they want to play this time. Sometimes we decide on interceptors having a chance to hit back even when getting hit, other times we would rather interceptors have a higher number to hit at, even if that means attacking hits immediately destroy them.

    The second method is far less appealing from an attacker POV.

    Below you can compare both + and - : sum between OOB G40 SBR and your HR SBR based on 1942.2 SBR:

    Here is the OOB ratio, of all SBR for reference:
    @Baron:

    So, from my last post, I can provide a simple fix to the issue of SBR being too much OP.

    Apply the OOB 1942.2 escort and intercept rules while keeping the damage value of Strat Bombers and Tac Bombers.

    Gives to all Fighters / Strat Bombers / Tac Bombers
    Attack @1 First Strike.
    Keep damage as G40 OOB: 1D6+2 for StB and 1D6 for TcB.
    Fighter Defend @2.

    Here is a discussion on the variant I showed in the last post.
    1942.2 Strategic Bombing Raid SBR, Bombers and escorts, Interceptors vs triple A
    http://www.axisandallies.org/forums/index.php?topic=34118.msg1311386#msg1311386

    Each escorting Fighter have preemptive first strike A1 but also gives a combined arms effect to all escorted bombers, which get A1 preemptive roll.
    It only needs 1 Fighter unit amongst the attacker SBR fleet to give all bombers their preemptive strike A1.
    When all by themselves, bombers only get a regular attack @1.

    That’s the small variants compared to OOB 1942.2 SBR rules, giving all StBs A1 First Strike.

    This means, for instance, that according to G40 OOB SBR with all planes @1, you will have a very positive odds whether raiding with 2 StBs or 1 Fg and 1 StB against 2 interceptors: + 2.445 IPCs or + 3.639 IPCs.
    With the 1942.2 SBR rules with 1d6+2 damage, both results give an even results for attacker or defender: - 0.001 IPC or -0.002 IPC.
    So, when your people choose the last one rule, SBR will stay even when you keep a 1:1 ratio of bombers & Fgs over defending fighters.
    For example: 3Fgs+3StBs vs 6 Fgs= 0 IPCs damage /SBR run on average.
    With OOB G40 SBR, 3Fgs+3StBs vs 6 Fgs= you get 3*+2.445 (1Fg+1StB vs 2 Fgs) = + 7.335 IPCs damage /SBR run.   A big difference, don’t you think?
