Is there a best order of sending missiles?

cruises, chems, nukes.

Would have said nukes then chems, cause with chems first you are nuking empty acres?

sfbob that only matters if your acreage is significantly smaller than the target. Otherwise you kill the same amount of buildings/acres in total no matter which order you do it, except the nukes increase the SDI of the target so fewer of the missiles will actually be effective if you send them first.

So in the normal case, and I don't say this often; but in the normal case Marshal is in fact right.

Don't send nukes to your Chem target or vice versa. Marshal is wrong!

if has single country to kill then nukes last, if war then targets posted as missiledumps (and if target is near dead on killrun then chems on it).
