Nope, not going to work.
You build 5 TRNs on G1, and UK KNOWS what you are going to try… only one thing you CAN do with that build (assuming they are all in the Baltic to assist with Sea Lion).
I am also going to assume that all AF were landed in Western.
Now lets REALLY go max force for London…
BB and TRN move to SZ13, and will take 1 ART, 1 INF from Algeria to London and add a BB shot
So, the response…
UK builds 10 INF. They may also suicide their BB and TRN to SZ6 to do some damage to your fleet and/or bleed some air cover off your attack
TRNs the ECan ARM to London
US sends FIG and BOM to UK, as well as 2 INF, 1 ART, 1 ARM
So, the attack force is:
6 TRNs loaded with 6 ARM, 6 INF
1 TRN loaded with 1 INF, 1 ART
To get that force, Germany needs ALL ARM from Western, Germany, Southern and Eastern as well as INF from Germany and Norway.
Germany will have 1 ARM left in Europe (assuming standard R1 open of West Russia/Ukraine) and 11 INF. That assumes NO LOSSES from attacks on G1
BUT… Russia will move again on R2, and will wipe out at least anotehr couple of forces, Germany will be down to almost nothing in Europe once they attempt Sea Lion, with a MASSIVE Russian force moving into Eastern on R3.
So it is an all or nothing shot…
Defensive Force is:
Running that battle through the sim, with the “take w/ 1 unit” option, because clearing it does you no good, you HAVE to raid the IPC for it to be worth it…
Germany wins 6.2% of the time
And a loss of ALL German units, including AF.
Not very good odds, especially with the West Russia Stack moving into Eastern on R3, and the UK hammering your TRN fleet with 1 BB, 2 TRN, 2 FIG and a BOM, then the US hitting with 1 DST, 2 TRN, up to 3 FIGs, and a BOM (WUS and Hawaii FIGs moved to ECan in US1)
Which is an average of teh entire German fleet being wiped out (in exchange for the US and UK AF and Fleets.
So on G2, Germany builds $35 worth of units to defend with.
On UK2, UK buys 3 TRN, and US2 sails 3 TRN, 1 loaded to London.
Also on UK2, Rome falls to the UK forces coming from India via Indian Fleet.
R3, Russia holds Norway, West Russia, Belo, Ukraine, Eastern and Balkans.
G3, Germany buys 10 more INF, so they have about 25 units total
By R4, Everythign except Berlin has fallen, which falls by **R5 AT THE LATEST
PLEASE, someone play me and build 5 German TRNs on G1!**
