First Fire & MG question
Hello:
"A berserk American half-squad three hexes away is charging
a German squad equipped with a MMG. (Doesn't matter for the
example, but that's what happened.)
The German squad wants to First Fire the Machine gun alone
after the 1st MP. If the Machine gun fires and retains rate
of fire, there's no problem. But if the Machine gun doesn't
retain ROF, on the other hand, (and doesn't break the half-
squad) it gives rise to the following:
The next MP the American half-squad moves adjacent to the
German squad. Can the German squad first fire its inherent
firepower and add the Machine gun's Subsequent First Fire?
Can you combine First Fire attacks this way? Or must the
entire attack be a Subsequent First Fire attack?"
Note that the Defending player could've laid down a fire lane down after the 1st MF (also infantry use MF, vehicles use MP) with the mmg as per A9.22 (2nd ed ASLRB):
"Whenever the DEFENDER declares a Defensive First Fire
attack with a Good order SW MG that is manned by unpinned
Infantry (even as ordnance or as part of a FG), he may also
declare a Fire Lane with that MG if it not already marked
with a First/Final Fire counter ..."
In this situation a Firelane would probably be a good idea since the berserker must continue charging the nearest keu as per A15.43 (obviously in this case the German Sqd & MMG). Note that declaring a MG firelane would've caused a First Fire marker to be placed on the MG (since the MMG lost ROF anyway it wouldn't have hurt it in that case). Also note, however, that you would've had to declare a Fire Lane as part of the original shot as per the previously quoted rule (you can't decide, for example, to lay a Fire Lane down after-the-fact, in order to see if the MMG retained ROF first). Had you declared a mmg fire lane you would've then placed a Fire Lane residual counter as per A9.22/A9.221 (depending on whether it was a Hex grain or Alternate Hex grain). With a Fire lane residual counter in place, and assuming the berserk half-squad survived its first MF DFF attack, the half-squad then moves using its second MF expenditure (bringing it ADJACENT to the MMG & manning squad, as per the example). I guess there were several options available depending on what the defender had done or what had happened.
If a MG Fire Lane was not placed & the MG lost its ROF, then the MG could fire as SFF combining with the squads FP (the MG fire would be considered sustained since it is marked with a First Fire counter as per A9.3) for an 13 + whatever DRM IFT attack [assuming a 4 IFP squad]{both squad & mmg would now be marked Final Fire as per A8.3}. However, as bprobst noted above if you shoot the mmg by itself {5 + whatever DRM attack: doubled and halved} both would be marked Final Fire as per A8.3 in this case too. Note also: 6 factor residual fire or 2 factor residual fire counters would be left in the hex (case A/case B) assuming no hindrances or wall/hedge tem reduced it.
If you had placed a MG fire lane during the first MF expenditure, the moving half-squad would now be attacked by fire lane residual fire (assuming it entered a hex of the MG's fire lane--more than likely considering a berserker's limited movement options). This residual attack would occur separate from other attacks & occur second in the case of MG firelane residual & normal residual FP counters hypothetically existing simultaneously in the same hex as per A9.222:
"If residual FP from a source other than another Fire Lane
exists in a Location of a Fire Lane, it must be resolved
separately prior to the Fire Lane Residual FP."
So, what would happen in this case is that the Fire Lane residual would attack the berserk half squad on its second MF and then you could shoot the squad's inherent FP (8+ IFT attack, leaving a 4 factor residual FP counter in the hex {along with the overlapping Fire Lane residual}). Both squad and mmg are now marked First Fire.
If the berserk half squad still lived at this point, it would enter the squad & mmg's hex, forcing a TPBF situation on the DEFENDERS who would have to attack as per A8.312:
"An armed unbroken Infantry defender not in Melee must
after all residual-FP/minefield/OBA attacks then
immediately attack any Infantry/Cavalry MMC unit that
enters its location during the Mph whether it uses
Defensive First Fire, Subsequent First Fire, or FPF ..."
If the squad & mmg are marked Final Fire then the attack would be a case of FPF (A8.31). If the squad & mmg have only First Fired then it would be a regular SFF attack (A8.3), however in the case of the squad having laid a MG firelane the firelane would be cancelled as per A9.223.
"The next MP the American half-squad moves adjacent to the
German squad. Can the German squad first fire its inherent
firepower and add the Machinegun's Subsequent First Fire?
Can you combine First Fire attacks this way? Or must the
entire attack be a Subsequent First Fire attack?"
Assuming the berserk half squad dies at some point during these attacks & another American unit moves adjacent, the squad's & mmg's fire options would be limited as befitted their fire status (per above). Note that if the original berserker died & the DEFENDERs were marked Final Fire they can choose to fire at the adjacent unit using FPF as per A8.31, but this is not mandatory as it is during a TPBF situation (A8.312).
There is also a Q&A on this same case, not sure of the Q&A's source:
A8.3 Subsequent First Fire (March 2003)
(Q) It is player A's movement phase. Player B has a squad
possessing a mmg. Player A moves a unit, and player B fires
the mmg only, at the enemy unit, but does not maintain ROF.
The mmg is marked with a First Fire counter. Player A moves
another unit into the LOS of this position. Player B
subsequent fires, again mmg only, at this unit. The mmg is
now marked with a Final Fire counter. Can player B's squad
still fire its inherent FP as First Fire and Subsequent Fire?
(A) No. A8.3 "... a squad may not split its usable inherent
FP from that of its MG/IFE during Subsequent First Fire
unless it opts to not use the remaining FP/SW at all." In
this example, the squad has "opted" not to use its inherent
FP at all.
One last thing to keep in mind: if the MMG was in a woods/building/rubble location its field of fire would be ‘fixed' as per A9.21 {and in your case, if the second U.S ATTACKING unit moved in on the squad & mmg from outside this now fixed CA, the MMG could not fire on it}.
Take it easy,
