in MP preview, just run a blue squad of 8 (vanilla weapon squad). All playable (or at least leader + marksman)
- play in MP : 1 as leader , 1 as marksman.
- or in SP: block the marksman by incapacitating it or surrounding it by fences (no move possible)
>>> as soon as marksman is player (JIP or not) the AIs (so not played in group) will follow marksman and will not obey to leader anymore (move orders are skipped *)
or.... if this nbr4 unit (marksman) is stuck, some units (all in vanilla weapons squads) will rally it, no matter the move order of the leader.
* more exactly, each order leads to the AI rallying the marksman (even if he's unconscious). To confirm, you can test 1st player as marksman, 2nd JIP as leader. All orders gives this weird result.
