Don't think so...
E3.712:
"...having Winter Camouflage receives a +1 LV Hindrance DRM when fired upon beyond eight hexes if Infantry ..."
So then I guess Winter Camouflage DRM would apply to the target hexes of a Strafing run (4 hexes = 8 Aerial Range - E.5) and the first attack of a Point Attack. It would not apply to a Bomb attack.
Forgotten War introduces a new element of Air Support, the TACP, which directs fire from a unit on the map. W9.113 "Ground Support" gives -2 DRM to a Sighting TC that is "reduced by one if there is an applicable LOS/LV/DLV Hindrance along the TACP's LOS between its Location ... and that of the aircraft's target hex."
E3.712 Winter Camouflage "receives a +1 LV Hindrance when fired upon if Infantry..." Since Winter Camouflage is considered a LV Hindrance would it apply to the TACP DRM? If not I would again assume it would apply to the attack if at 8 hex Aerial Range, but if the LV Hindrance applies to the Sighting TC would it also apply to an attack at 8 hex Aerial Range?
