[WarInEur] supply and the CWIE written rules

[Wardall Clark]

Thanks Steve: > 
In past posts I made a few mistakes.   
AS I noted previously, the game has 4 sets of official rules at present.
1) The code for CWIE-1 
2) The written rules for CWIE.  I think these are primarily the work of Dan Lazov. 
3) The written rules for the latest release of BWIE
4) The "clarified" rules from the decision game website.
As the computer games know to their sorrow, neither CWIE-1 nor CWIE-2 currently conforms to (3) 
 
regarding the details of supply, all the discussion has been on what is found in (3) and (4). 
the CWIE rules read as follows
 
6.2 Supply Sources and Supply Heads
     Most countries have one or more Supply Sources in their country.......supply is spread over
rail hexes and through ports to the seas and then on to other ports as well as through
mobile supply units--all are Supply Heads
 
If a Supply Source is connected to rail, the supply will travel as far as the rail will permit--there is no
movement limitation. .........Each supplied Rail hex will then become a Supply Head.
 
Supply can be traced into any sea <for> which the player has naval transport capacity.....and in which either
there is a supply source which is a port in that sea, there is a friendly port that is connected by rail to a supply source,or a
naval path can be be traced into that sea from a supplied port in another sea. If these conditions are met, supply can be 
traced through that sea and into any friendly port or beach head, making that port or beach head hex into a supply head.
 
Supply Sources are always of Major supply Supply Heads are of Major supply unless they had to trace supply at one point through
a minor port or through a beach head. Any supply Head that had to trace supply through a functioning minor port (such as a damaged
major port) has minor supply. ...........
 
6.3 Tracing Supply to a Supply Head or Supply source. 
     All units must trace supply from their hex to a supply head or supply source. If the unit is tracing to a supply sources, or to a rail
supply head, or mobile supply unit supply head, then it has 10 movement points<with which> to trace supply to that supply source or
supply head (6 MPs for the Russians)  If the unit is tracing supply to a functioning Minor port is has 4 MPs, and if it tracing supply to 
<a> beach head Supply hex it has 1 Mp (or one hex minimum).
 
For example, if a Mobile supply unit was tracing supply to a Minor port hex, it would need to be within 4 MP of the port. Any unit tracing 
supply to Mobile supply unit would need to be within 10 MPs. The supply traced through the minor port and then through the mobile supply
unit would be minor supply. and therefore, for instance, no air air assault missions could be based from those hexes. 
 
Supply is traced as if an imaginary infantry unit was moving from that hex to the supply head or supply source. ZOCs and Air interdiction are
ignored when calculating the cost in movement points to trace supply, but supply cannot be traced through a hex in enemy ZOC unless it is
occupied by friendly units. If a unit cannot trace supply to <any> supply source or supply head the unit is out of supply.
 
6.4 Mobile Supply units. 
Mobil supply units can act as a Supply Head to whatever supply Source or Supply Head they can trace supply to. A line of Mobile supply units 
could be made, all within 10 MPs of another Mobile Supply unit, as long as one of the Mobile Supply units as within 10 MPs of a supplied Major 
Port or rail line, 4 MPs of a supplied minor port, or 1 hex of a supplied Beach Head. The quality of the Mobile Supply Units supply head.......will
depend on the quality of the supply head it is tracing supply to. If a Mobile Supply unit is functioning as a supply head and, it is on a rail hex 
that is otherwise not connected to a supply source by rail, then supply from the Mobile supply unit will be spread through the rail hex to any 
other connected rail hexes and they will all function as supply heads. 
 
       This makes it quite clear that the MSU has to be sitting on top of some part of the friendly the rail net in order "energize" that net with supply.
The Decision game rules make this equally clear with a few words in parantheses that make it clear that the bridging of a transportation hit by a single 
MSU is actually a somewhat anomalous use. I had this one wrong
 
Another mistake I made is that I wrote that resources access could be resumed by putting a MSU on top of a cut or T-hit.  This is not such, available 
foreign centers are generally denied unless the axis could move a unit by rail transport from the center into Berlin strictly by rail movement.) As enemy 
units, T-hits and cuts would prevent this, the only thing that an MSU in the break can accomplish is to restore supply. 
 
I happen to agree with steve that the needed MSU to patch multiple hits might be rather large, but given the the extent to which the there in redundency
within greater germany, it probably would not handicap the axis too badly if restoring supply around a T-hit was treated uniformly with the way MSU are used 
to bridge other cuts.  
 
With regards to ports.  The rules make certain major ports into supply sources for certain nationalities: 
Russia may treat leningrad, Odessa, Sevastopol and Riga as supply sources.  Germany may ship supplies from Stettin. The Americans treat friendly High Seas ports as Supply Sources.  The British Isles high seas ports are supply sources.  These ports don't need a railroad link order to spread supply's into the adjacent sea zone.
 
The only way all other ports get supplies by sea is from these ports, or some rail-linked port. That supplying port doesn't have to be in the same sea zone, but it has to be somewhere that could legally send a ground unit by sea transfer.   Thus all this talk of port to port to port transfer of supplies either is essentially rubbish (as such a transfer would be unnecessary,) or one of the ports involved was a supply source, or there was a some land transfer as part of the chain of supply. 
(e.g.  Southampton feeds Antwerp, whose rail line feeds Kiel, whose port feeds Konigsburg with supplies.) In real WIE it is hard imagine a situation for which such a journey would actually be necessary, since not only does sea supply have unlimited range, but associated players cannot share naval or rail capacity
