Zone of Interception

[Mehrunes]

Last weekend the following question came up:
Can the HF intercept the LH, which is declaring a charge on a (invisible) BG to the south?
The terrain is rough terrain.

In Germany this would have been commonly ruled that it cannot with the simple explanation "a interception cannot go through disordering terrain", but doubts arose if this is exactly what the rules say...

Basically, it is a question if the ZOI is treated like a "carpet" which extends over the whole front of the unit until it meets the first obstruction and is then stopped everywhere or if it is treated like a "flash light" which might be stopped by an obstruction somewhere on the front of the unit, but may go further somewhere else.
In the second case, the ZOI would reach to the LH and the interception would be legal.

It's a carpet. Because you can't contract in an interception charge, so you would enter the terrain.

The rules actually say

It [the ZOI] extends ... only through terrain that does not disorder or severely disorder.
...
An interception charge can be up to the limit of the battlegroup's ZOI

So even though part of the LH BG is in the ZOI, in order to make contact the foot would have to move beyond the limit of the ZOI where it is limited by the terrain, hence the interception is not allowed.

i.e. "You can't intercept through disordering terrain" is not the exact rule wording, but it is normally a consequence of the rule wording. Note however, that the intercepting BG could start partly in disordering terrain as long as none of the terrain is in in the ZOI in front of the BG. [/quote]

Thanks, I missed the part that says "up to the limit of the ZOI".
I stopped reading after the terrain part. :-/
