Based on the articles by Jeff Petraksa in C3i #'s 1 and 3 (the PDFs for which are available on GMT's web site). This is for the original Hornet Leader published by GMT.
The TDA (Tactical Decision Aid) lists all the weapons and pods available and details the average number of hits or wingman intervention percentage for AAMs and cannon by AtA modifier, the average number of hits against standard or underground target for AGWs and cannon by AtA or AtG modifier, and the effects of pods.
You'll use the TDA to help decide how many AtG aircraft carrying which munitions to assign to a mission, and how much top cover to take. Or at least be left in no doubt as to the tough tradeoffs you'll have to make!
Also included in the PDF are replacements for the Air Combat, Ground to Air and Air to Ground charts.
The TDA and charts consolidate the variant material presented over the years in Thunderbolt Apache Leader, C3i magazine and Dave Schueler's unpublished Alpha Strike & Kola Strike variants (available on BGG and Consimworld).
