As discussed in #998 as to "To Do", so listing here so it's not forgotten. See also the list in #941

As of PR #998 , the raid mechanism uses the following int when specifying the maximal number of vehicles in a raid
int attack_vehicle_count = 2;

Skin36 has said that the OG uses the following formula

attack_vehicle_count = (bld_count+veh_in_org-1)/bld_count
max(attack_vehicle_count) = 5

This should be opened up to modding and the Original Game formula should be implemented (or improved) once Organisations are made to buy/sell vehicles from their garage(s) (also curently a To Do which I'll make a separate PR for - see #1000 )
