Turn 22. Mar/Apr 1943. Axis #9. The Eastern Front. Attack Planning - Sevastopol.
(1) With fine weather in the Crimea and his forces including air support in position, OKW orders von Leeb to get on with his assault to take Sevastopol.
(2) von Leeb will personally move his HQ reserves (HQ-I) in position to provide +1 in offensive HQ support.
(3) Directly east of Sevastopol is a German mot eng div (2 factors) that will allow all units in that hex to attack the fort at full strength.
(4) von Leeb can muster his HQ reserve forces, 3 corps & 2 divs for a total of 24 AF vs 8 DF.
(5) He also has at his disposal, 2 artillery divs, 2 Luftwaffe stuka wings, 1 fighter-bomber wing totaling 20 TAC factors.
(6) If all TAC factors are used in ground support then this would produce 44 AF w/+2 vs 8 DF w/-1 -> +12A (85% PWIN).
(7) However; von Leeb is faced with the decision if he should use any of these air or artillery units for ground strike(s).
(8) Of course, he'll make the final decision but he puts the problem back on his staff to work out the details and summarize in a form that will allow him to make an intelligent decision.
(9) His staff decides that the potential ground strike package will be the 150 mm arty div (4) & Ju 88A1 Stuka wing (4).
(10) The remainder, totaling 12 TAC, will be used in ground support IF von Leeb decides to go with the ground strike package. If not, all 20 TAC will be used in ground support.
(11) The rationale for the ground strike package is that its 8 total TAC equals to the 8 DF so at worse a complete miss (12.9%) will drop the assault odds by 2 to +10A (72% PWIN).
(12) One hit (46.1%) will give the same as if an all ground support attack (i.e., +12A, 85% PWIN).
(13) Two hits (41%) will raise the assault to +14A (94%).
(14) von Leeb's staff works out the expected PWIN for the ground strike package which comes to 87% and which is only a +3% improvement over the +12A guarantee odds for full ground support.
(15) Honestly at this point von Leeb hasn't decided what to do and he's apparently going to stop here for the night, enjoy a whiskey and an episode of "Murder She Wrote".
(16) If you would like to chime in please feel free to give your opinion as I find all this fun and hope you do too.
