No, I am not. I am saying that any unit receiving the -1 FFMO is moving in Open Ground. Saying I am arguing that a FT makes everything move in OG isn't so no matter how often you bring it up.
Here:
Key point here: -1 FFMO DRM is moving in Open Ground. Compare that to what I said just a moment ago.
Now, lets build the rules chain to see what happens when a unit is moving on a hill hex and receives fire (hypothetically in the case of routing or concealment gain loss):
Note the reference to A10.531 and that "most fire traced from a lower elevation" is subject to +1 for HA. Key point "Most", not all, and the reference to A10.531 (see above).
Notice, if you are receiving Direct Fire from a lower elevation you are entitled to +1 HA. Also notice that is says A unit eligible for the +1 TEM for Height Advantage is not subject to Interdiction/FFMO by an attack to which that +1 TEM applies.
And lastly:
Mortars and OBA are Indirect Fire, not Direct Fire. So, if unit is moving in a hill hex, in otherwise Open Ground, and fired upon by a lower elevation unit manning an MG, they are receiving Direct Fire and eligible for a +1 HA DRM. If instead, that firing unit is manning a mortar, such fire is Indirect Fire. As Indirect Fire, the +1 for HA is NA. If a unit is not eligible for the +1 HA TEM, they ARE subject to -1 FFMO. As they are subject to -1 FFMO, they are moving in Open Ground as defined by A10.531.
While we are at it, lets take on this:
This does not say the TEM varies depending on the incoming fire type (as B10.31 does), it just says the TEM DRM is NA vs this particular attack. The TEM still exists, it is still +? depending on Terrain Type. The TEM would still be +1 HA and the +1 DRM would be NA to the FT IFT DR. Why is this you ask? Because a FT is using ... (wait for it) ... Direct Fire. -- jim
