We’ve been dropping everything up to tanks from the back of 130’s. I think a motorcycle would be no problem. Note that motorcycles were listed in the cite I gave as part of the inventory for special forces troops. To transit a short distance motorcycles would be the logical choice.
The air to ground weapons would be deployed by aircraft supporting an operation. Either the same aircraft delivering the SO group or additional aircraft. The surface to surface weapons would be brought in with the group as hand held weapons.
I think it comes from the inventory of equipment set up to operate the Special Operations group. Where do you think it would come from?
Nothing I’ve suggested is particularly high tech. It’s standard military hardware assigned to troops trained to use them. I haven’t suggested anything remotely high tech or complicated beyond a rapid deployment of well trained troops.
