A/F Rules Module

Abstraction A/F rules module is incorporated in many other variants, such as
Deluge. However as it stands it
could be argued that the Abstraction rules are not suitable to be lifted
wholesale. The following module
does differ from the strict Abstraction rules in several respects, namely:
I have abandoned the rule that A/F combinations may only exist for 3 consecutive
moves and that the GM must force units to retreat even if no retreat is ordered
as there is no particular reason why these rules should have universal
This revision states that embarkations occur prior to simultaneous movement and
thus cannot fail and disembarkations occur during simultaneous movement and are
thus affected by what other units do.
changes ensure that the rules are more logically consistent than those in
Abstraction without the necessity of introducing complicated time phases as used
in variants such as Mercator. However,
it should be noted that they do produce different result in some circumstances
to the A/F rules as they appear in Abstraction.
Move Sequence. Embarkations are
adjudicated prior to simultaneous movement. Disembarkations occur during simultaneous movement and are adjudicated as
being simultaneous with and independent of whatever happens to the fleet element
of the A/F.
Fast Ferry. A convoy as described
in the Diplomacy rulebook is limited to the crossing of a single sea space via a
single fleet. To avoid confusion
with A/F convoys, a regular single space convoy is referred to as a "Fast
Ferry" ("FF")If a fleet attempts to FF an army, but is unable to
disembark the army, then the army remains on board the fleet and an A/F is
formed (see below).
Embarkation. An army may embark on to a fleet in a sea space (not a coastal
space) before simultaneous movement is adjudicated and thus a legal embarkation
move can never fail. If an army has
embarked on a fleet and cannot disembark for whatever reason, it will remain on
board the fleet as an A/F.
A/F Operations. A convoy of more
than one sea space can only be undertaken by the formation of an
"Army/Fleet" ("A/F") to carry the army on board. In a given move, an army may board a fleet in an adjacent sea space (thus
creating an A/F), the A/F may them move to an adjacent sea space, and the army
may then also disembark the army into a coastal space adjacent to the second sea
space. For example, A(Lon) boards
F(ENG), A/F(ENG)-MAO, A disembarks Por.
A/F has the same combat value as a single fleet and may attack, support and be
supported, but it may not FF. An
A/F may support operations in coastal provinces and it may do so with a value of
two (fleet and army), although it may never enter a coastal province itself.
Disembarkation. Disembarkation is
simultaneous with other movement, thus an army may disembark from an A/F at the
same time that the fleet is moving elsewhere or supporting another action. For example, A/F(ION) disembarks A(Tun), F(ION)-EMS. However, if disembarkation fails, then the A/F remains intact and any
fleet movement (but not support) will also fail (because if it succeeded the
army would be left behind to drown).
follows that if an A/F is disembarking an army then the fleet element may use
its move to support the disembarkation of the army. For example A/F(BLA) disembarks A(Sev) S by F(BLA) will
displace an unsupported A(Sev).
an A/F attempting to disembark an army attempts to move or is dislodged, then
the disembarkation will be unaffected as it is considered independently of the
Exception. In order to avoid circular reasoning, there is an exception to the
general rule that disembarkations are simultaneous with other movement. The disembarkation of an army from an A/F, which in turn would have had
to move successfully to be in a position to disembark the army, may not have an
direct or indirect effect on the success of the movement of the A/F in question,
and if it does so the disembarkation will fail.
example, consider the following orders:
A/F(NTH)-ENG, disembarks A(ENG)-Bre, F(MAO) S disembarkation A(ENG)-Bre
result will be that the French move to Brest succeeds and England will have an
A/F in ENG. The reasoning here is
if the English disembarkation in Brest succeeded, the French move F(ENG)-Bre
would fail and therefore the English move A/F(NTH)-ENG would fail. Thus the disembarkation has a direct effect on the success of the
movement of the A/F it came from, therefore the disembarkation fails.
Retreats. If an A/F is forced to
retreat to a coastal space, it reverts to a fleet and the army is disbanded. An army may retreat on to an adjacent fleet in a sea space and create an
Circular reasoning. In the event
that any movement cannot be adjudicated due to circular reasoning, then all
units will stand.
