Mmmm..je doute, 23.6 dit qu'on peut la lancer "adjacent" d'une upper ou lower location :
"[...]or down (e.g., from an upper-level building Location or across a cliff hexside) to the ground-level,
in-LOS Location of an adjacent hex or to the ground level of a non-Interior
Building hex from a higher level Location of that hex (even though there may
be intervening building levels)[...]."
Il y a également ces Q&A :
A23.6 Is there any restriction on the number of
levels up which a DC may be thrown to an
adjacent Location? Also, can Height Advantage
apply to thrown DC, for either party?
A. One level. Yes, if the DC is thrown across a
Crest Line to a lower level and the thrower is
claiming no other TEM. [Letter8]
A23.6 May a DC be Thrown from an upper
building level to the in-LOS, ground level
Location of an adjacent hex? Can either/both
Effects DR for a Thrown DC cause its
malfunction?
A. Yes. No – only the first such DR. [An93b;
An96]
A23.41, A23.6, & B24.11
A squad at 1st level of a building throws a DC in an adjacent road hex. Rolling the effects against itself, the DR is an Original KIA
(i.e. 2 to 4). Here are the questions this situation arises: 1) Can a thrown DC create Rubble – cf. B24.11 dr? 2) Does anything
happen to units at Ground Level of the building?
A. Yes, but only in the DC’s original target Location. No.
