happy hermit: may be it is because I am very passive player:) I see your point, but I think it could be very danger if radar is in midst of attack - with ejected aerial it cant move so it blocks own forces and using scan action costs time. May be there would be rule, that after 4 moves w/o action aerial automatically plug in and it cost one turn or so,but it llooks a bit complicated.

For attacking players there shold be parrachutist. It can move by two fields, also jump over vulcano (not ash at all:) and other stones. If landed on occupied field fight will start, if parrachutist win or if field is unoccupied, parrachutist also see all adjusted fields. Move restrictions - parrachutist can move by 2 fields every turn, but jump over occupied field once in two turns. Also after moving by two fields parrachutist is revealed.
