Je dirais oui car :
3.4 MULTIPLE TARGETS: A hit obtained on any TH Table affects only the target hex and, depending on the Target-Type/applicable-DRM, not necessarily all the occupants of that hex. Not all enemy (and Melee) potential targets in a hex/Location are always hit/affected, because some of them might be immune due to qualifying for TH/Effects DRM not applicable to others
edit : oula, j'ai un doute en me relisant :
depending on the Target-Type/applicable-DRM
la suite :
3.33 ... All (including friendly) non-Aerial units in the target hex can be hit (even by WP), except for those immune as per 3.4
3.4 spécifie cependant :
some of them might be immune due to qualifying for TH/Effects DRM not applicable to others
bref, je brasse du vent mais je ne sais plus quoi penser, instinctivement je dirauis que si on touche ne serais ce qu'une unityé, toutes sont afectées par l'area, sauf celle hors LOS, EXC : mortars.
