The "Coordinated Strike" operation has high requirements (high network, many spies for operation, wargoal needed) and its effects are only short. (3 days)
Therefore the bonuses it gives can be VERY powerful.
I would suggest that you can choose between:
- Bomber (Nav, Tac, Cas) Port Strike Damage + 1000% (This is the pearl harbour thing. Make it possible to severly damage a fleet stationed in a port)
- Fighter Air Damge +1000% decreasing slower if no enemy air (This is the barbarossa thing. Soviet can decide to not put up planes and fight for 14 days under red air or put up air and have heavily losses. This is also useful for Naval invasions to get green air)
- Mountain Attack Terrain Debuff = 0% (If you attack a land with a defense line in the mountains you can for 3 days attack in mountains as if it was plains. Useful to break a mountain defense line)
- Land Fort Attack Debuff = 0% (If you attack a land with a defense line with forts you can for 3 days attack the forts as if it was not there.)
- Supply Grace +1000% (You can go deep into enemy territory without supplies, e.g. to secure a port.
- Naval Light Attack, Hard Attack and Piercing +100% for 14 days (To get a big advantage if you expect a big naval battle soon in the war.)
- Sub Detection = 100% (For the first 3 days of the war the subs are 100% visible.)
What's your opinion?
