I told you that I was going to make 2 invasions with the USA during the Surprise impulse against Germany. Here is the first one. It's a semi-risky attack on the Azores. This is also one of those situations which gives the defender a better chance if they do not include the Notional Unit. Since it is both surprised and out of supply, it would add no combat factors while giving the USA a +1 die roll modifier.
The mechanics of the game favor the attackers here, though. The 2.5 attack factors get rounded up to 3, and the 2.5 Shore Bombardment factors also get rounded up to 3. So a 5:1 attack becomes a 6:1 attack . . . and while it may not be the most brilliant idea, I'm going to take the 40% shot at HQ Support. If that succeeds, this becomes a 7:1 Assault. In most situations, this is better because it increases the chance of remaining organized from 50% to 70%, but in this case, I'm doing it to reduce the chances of losing the HQ from 20% to 10%. I figure that even though a disorganized HQ can't reorganize units or make more moves in the turn, a dead one can't do that either. Anything that improves the chances of survival is a good thing.
The bold sentence is actually incorrect. You only get 2.5 land factors, so you can only add 2.5 shore bombardment and/or 2.5 air support. Afterwards, you round to either 3, 5 (no rounding), or 8. The game engine calculated the odds correctly in the combat screenshot, 5:1.

You're the one who told me that Leningrad could survive on 2 units. [&:]
I'm not familiar with the 1D10 charts, but under 2D10 rules (yep, you're not using them) it's
possible to lose the city. 11 attacking factors : 16 defending factors -> 2:3.
+1 odds
+3 flipped defending units (assumption)
+1 HQ attacking city
+1 HQ support
-1 city
-2 printed factories
-1 engineer defending city
_
+2 DRM (net)
Modified roll of 20+ will result in the city's loss (19 clears the hex but kills both Finnish units.) No idea if it's still possible under 1D10 rules.
