There is ONLY 1 time that the attacker gets to choose defender losses…
In a multiplayer game where multinational forces are attacked, and the defending players cannot decide, the Attacker decides.
can fighters (when going on board in an aircraft carrier) get involved in an amphibious assault? (if the adjacent sea zone is unoccupied)
yes, provided that movement-space limitations are met.
who would want an assault w/o air support
Someone who is nuts or is using tanks.
or has bb´s in the area, or is using 6 inf vs. 1 etc.
