First off let me say the attitude / snarkiness is not appreciated at all.
Next there is Navy involved and there will be FM2s (Martlets) and Seafires involved.
Right now I am working out the particulars of a possible amphibious invasion. The last time I did this in 2005 I found that the HE round of the LVT4 did no damage at all to other vehicles, including light skin vehicles such as the M3. I need to do some testing but what I thought that might be fun is to see if could find a spot with shore guns and a base nearby. Then have a fleet of DDs park off the coast and offer fire support (dueling with shore guns) while the LVTs went ashore and tried to take the base. If the LVT4 75mm HE round still does nothing against any vehicle. Then basically I need to make sure the opposition is just armed with machine guns since the LVTs will only have those to take out enemy vehicles.
So right now I am looking at the SdKfz 251 or M3 as the main German / Italian opposition vehicle plus, might throw in some jeeps (armed with 1 .50) to give the Axis a vehicle that is really mobile at the cost of no armor at all.
That is why I included the jeep even though I might not use it.
Oh, and no for any of the ground battles it will not be a 2 hour event but more of a 50 minute event and then a second life in an airplane.
