ok you’ve cut down to 31 items
these 6 are actually already in:
Phase 1: Economic Attacks        1
Phase 3: Air Movement        1
Phase 4: Land Combat: Anti-Air        1
Phase 4: Land Combat: Defender Retreat        1
Phase 4: Land Combat: Hit Allocation        1
Phase 4: Naval Combat: Hit Allocation        1
so 25 left
from those, these 15 are simple yet major in gameplay
so we’ll have them:
Phase 3: Airborne Drop        1
Phase 3: Air Reinforcement: Defensive Air Support Mission (DAS)      1
Phase 3: Naval Transport      1 
Phase 3: Naval Occupation    1   
Phase 4: Retreat Decision  1     
Phase 4: Land Combat:  Attacker Retreat      1
Phase 4: Land Combat: Air Units    1 
Phase 4: Land Combat: Air Units: Air Superiority      1 
Phase 4: Naval Combat: Attacker retreat        1
Phase 4: Naval Combat: Air units      1 
Phase 4: Naval Combat: Anti-Air        1
Phase 4: Wolf pack        1
Phase 4: Economic attacks        1
Phase 5: Air Transport        1
Phase 5: Non-combat Reinforcement    1
the remaining 10 I find are either complex or not major
you shall defend them, or we simplify or remove them
lets hope we keep it “lite” !
we want a small subset, not AARHE with just a few rules removed
Phase 3: Naval Movement      1 -> might be a bit complex for lite to roll dice even before combat
Phase 3: Submarine Movement  1  -> might be a bit complex for lite to roll dice even before combat
Phase 4: Land Combat: Air Units: Jet Superiority      1 -> not major, not core to gameplay
Phase 4: Naval Combat: Air Units: Jet Supremacy        1 -> not major, not core to gameplay
Phase 4: Naval Combat: Submarine Warfare    1 -> AARHE hit allocation already sorts out a lot, we could remove this paragraph, which’ll merely removes first cycle bonus
Phase 4: Naval Combat: Anti-Submarine Warfare (ASW)    1 -> a bit complex for lite, we don’t want players to have to allocate air/naval units to ASW resulting in a complex combat seqeunce
Phase 3: Air Missions        1
Phase 4: Air Missions          1
Phase 4: Counter-Air Mission (CA)        1
-> I think “air missions” sounds complex for lite, could do with just the 2 most important moves, SBR and DAS, SBR rule is already in and that describes the AA and dogfight before SBR rolls
Phase 5: Air Movement        1  -> lets just use OOB for NCM air movement? NCM air is not that major
Phase 5: Strategic Redeployment (optional)      1  -> this is optional in the first place
