Arming the Omega ships

[Legbreaker]

Small flaw to your idea - OPORD OMEGA states in section 3. "Execution", subsection e. paragraph 1) "to turn in vehicles and heavy equipment".
Additionally, Section 2. "Mission", states "Vehicles and heavy equipment will be transferred to FRG prior to departure".

I'd say artillery, AA guns and the like could well be classified as heavy equipment. Might see a few machineguns and shoulder fired AA missiles, but as the latter are somewhat rare by 2000, and the task force isn't likely to be attacked from the air (especially as they're leaving and therefore not an economically viable target for the scarce Pact air assets), the escorting warship(s) should be sufficient.

And don't forget they're German ships burning German oil. The Germans have the upper hand here and can pull the pin on the whole operation if the Americans try to smuggle something aboard they're not supposed to.
