I would like for the US and UK to be able to send lend lease (LL) to Russia, and the US to also be able to lend lease to the UK. With that in mind I’m sticking to the Euro side (but you could expand). My intention is to replace the existing Russian lend lease NO, and allow the Western Allies to give Russia IPCs and units. I’m not sure if it would keep UK ftrs out of Moscow but you could install a 3 IPC NO strictly for no western allied units in Russia to help with that as well (maybe 5 IPCs if needed).
Here’s my thoughts:
Sending nation doesn’t have to be at war, but receiving nation needs to be at war with one of the Euro axis powers (either Germany or Italy). Lend lease can be units, IPCs, or combination of both. Certain conditions need to be met for the nation to get the lend lease, and there is designated territories where the LL shows up (see later).
As the sending nations the US and UK can buy lend lease dice for 2 IPCs each during their purchase units phase (paid to the bank). US can buy up to 3 LL dice, but can only allocate 2 LL dice to any one nation (either UK or Russia), and UK can buy up to 2 LL dice (for Russia). You then roll the dice to determine the amount of lend lease that each nation will receive from the bank (sum of dice that was allocated to that power). The sending nation will ship the lend lease immediately, but it doesn’t arrive until the receiving nations turn (considered at sea and held out of play). At the beginning of the receiving nations turn if the following conditions are met the lend lease will arrive.
For the UK, there can be no German subs/war ships in the Atlantic (excluding sz112), and LL is received in United Kingdom (London). For Russia there can be no axis war ships in sz125, and LL is received at Archangel (must obviously be controlled by Russia).
Using the US for an example they buy 1 LL dice for 2 IPCs (pay bank). They roll a 5, so that is what Russia will get in units/IPCs through LL (the bank pays this not sending power just like it was an NO). If you rolled a “1” then Russia gets 1 IPC (guess the rest is considered lost at sea lol). For the 5 IPCs in LL the US decides to send an art (use Russian art) plus the extra 1 IPC (for a total of 5 IPCs LL). Again the LL is considered at sea until Russia’s turn (held out of play). In the beginning of Russia’s turn if there are no German war ships in sz125 the new Russian art is placed on Arch, and the 1 IPC is added to Russia’s bank. The art can move during Russia’s combat move phase, so it is probably better to send units if you can, otherwise it takes a while for the Russians to buy units and get them placed.
If sz125 is not clear, or Arch is taken then LL continues to be held out of play and you can attempt to deliver LL on Russia’s next turn. You could also re-appropriate it and send it to the UK next turn (swap Russia art for UK). However the nation that was unable to deliver LL can’t send more LL until it is delivered. If LL can’t be deliver after 2 attempts it is lost.
If you rolled 2 dice for LL to Russia (paid 4 IPCs) and ended up with a sum of 10, you could ship a ftr or a mech & tank etc…of coarse you could get screwed and roll snake eyes.
To make it more interesting you could add in other lend lease routes to Russia with similar conditions. Like through Persia (sz80) or Amur (sz5) so you have other ways to get LL to Russia if the northern route is cut off.
Could also lay out actual lend lease routes from US to UK/Russia, and from UK to Russia for the allies to keep clear of axis war ships. If not not clear can’t use that route, or allow enemy ships to attack lend lease because it would have to pass through a hostile sz.
