That may or may not be. I do not know. All I know is what the rule says: the Wreck hindrance is replaced with a +2 SMOKE hindrance but for two cases. I agree there seem to be limited cases where the Fire Lane were already established but they do exist. And from where I sit, the Wreck ceases to exist in almost every case (see the two exceptions). Since it ceases to exist--being replaced by a +2 SMOKE TEM--the "hard hindrance" also ceases to exist.
Interesting discussion though. I believe we are at the point where we must agree to disagree absent a Q&A. -- jim
Given the case we are talking about, i.e., established Fire lanes, is one of the two cases where the Wreck Hindrance DRM is used, it is not clear to me why it would not be used, and given a Wreck hindrance is defined as a hard hindrance (whose definition only applies to Fire Lanes) it is not clear to me why you would not consider it a hard hindrance when used with an established Fire lane.
The Q&A that does exist, which I quoted earlier in this thread and requote here, although not answering as clear as I would like, still answers the question.
"Q: B25.2 states that the wreck hindrance applies to any already established firelane. Does it apply to any firelane, or only a firelane established before the wreck began to burn?
UA: The wreck Hindrance applies normally (e.g., if it is not considered moving). "
So it is stating that the Wreck Hindrance applies normally, giving the example whereby it would not apply if it was considered moving. That answer is what has guided me to my conclusion, i.e., any established Fire lane (i.e., one that is actually in place at the time a unit moves into a Location of that Fire lane) uses a Wreck Hindrance DRM instead of the SMOKE DRM if said wreck is burning, and uses it "normally" (e.g., a wreck hindrance is applicable only if it is not considered moving). If the wreck hindrance is valid (e.g., not considered moving) it is a hard hindrance and applies to an established Fire Lane. A9.22 explains the mechanics of "placing" a Fire lane. The rules use the term "establish" within the A9.22 Fire Lane rules 3 times, once in A9.22, the last sentence "A MG that has
established a Fire Lane may not fire again until the DFPh...", once in the example "The existence of any obstacle(s) in Z5/Z6 would not prevent the HMG from
establishing a Fire Lane to/past EE6 ..." and once in A9.223 "A MG may cancel its Fire Lane in order to gain freedom to fire elsewhere (/its manning Infantry may use Subsequent-First-Fire/FPF after
establishing the Fire Lane) only if a TPBF/CC-Reaction-Fire situation occurs.."
I would infer that the term "established" refers to a legally placed Fire Lane, i.e., when a MG places a legal Fire lane, that Fire Lane has been established. The term distinguishes between a Fire lane being declared and placed and one that is now established.
This makes complete sense.
Case 1) An existing burning wreck is between a German 4-6-7/HMG/9-1 ldr stack and a non-assault moving unit. The Defender stack declares a DFF shot, including the placement of a Fire Lane. The attack is resolved using +2 SMOKE, -1 FFNAM, and -1 Ldr mod = net +0. The attack leaves no residual (4 / 2 reduced 2 columns for the Smoke DRM) but places the 4FP Fire Lane through the Location to its target hex. After that moving unit completes its move, another unit non-assault moves through a Location of the Fire Lane which is behind the burning wreck. That 4FP Fire Lane residual attack also gets a net 0 DRM (+1 Wreck Hindrance, -1 FFNAM).
Case 2) An established 4FP Fire Lane is present. An AFV moves through it, and while in a Location of that Fire Lane, it is attacked, killed, and left burning. An infantry unit then moves through that Fire lane, behind the now burning wreck. The Fire Lane residual attack gets a net -1 DRM (-1 FFNAM) as the wreck hindrance is NA due to the wreck being considered moving. Note that the Smoke from the burning wreck does negate FFMO (B24,2) but its DRM does not apply to Fire Lanes residual attacks. If the AFV did not burn, but was just destroyed, the Fire lane residual attack would get a net -2 DRM (-1 FFNAM, -1 FFMO) since the wreck hindrance DRM is NA due to the wreck being considered moving.
For Fire lanes, the Wreck Hindrance DRM is applied normally, regardless of whether the wreck is burning. If it is considered moving, no hindrance, if it is not considered moving, +1 hindrance.
IMO that is what the rules, clarified by the Q&A, say.
