1. The Germans released all surrendered Greek prisoners right away. So no there is a large reserve of already trained soldiers.
2. The police is anything but non existent, both the cities police and the gendarmerie were left in place and continued to operate through the occupation and after the liberation. Same for the civil service which was operating. As for the resistance, of course it will be integrated into the army and one notes it's military organisation was following that of the pre-war army in the first place.
3. Is a legitimate concern, but one notes that the calculations are leaving a 44% overhead already and say mostly nothing of manpower older than 35.
4. This was covered in the previous post, including US army sources available online. There is sufficient equipment in 1943 for up to 8 divisions in the US. I'd question myself if there is sufficient shipping to move that to Greece. But still the allies have already made here an initial commitment similar to Italy with 9 divisions landing in Greece. If you need 12-15 divisions or more in the Balkans to the end of the war they need to come from somewhere and the only reasonable source of manpower is locally.
1. First thing first, I didn't know that, and it goes a long way to explain the level of partisan activity during the occupation (that and the fact they resistance movement got their hand on an important part of the Italian matériel in 43).
I must ask if you (or anybody) knows why the release? Was it a logistical point? An racist one? Does the fact that the nearest Allied base was more than 500 km away was taken into account? Because with Crete staying in Allied hands might prompt the German to keep at least part of the prisoners under guard.
2. Like in France OTL, it doesn't mean they are not wholly seen as collaborators and that the resistance movements, particularly the communists ones, aren't better armed than them. And OTL they weren't enough to prevent OTL.
The way I see it, the second line units provides the security and labor duty, and keep the young men under control, until (or if) the matériel and equipment is made available.
3. I still think you under estimates the general disorganization from the 2 campaigns and the occupation
4. I was just saying that the Greeks won't be the first priority, even if the shipping ITTL is less tight than OTL, and if the US production is ahead of OTL.
Clothing and food were scares during winter 44-45 in the French Army (My grand-father was part of the Colmar Pocket campaign and the few stories he told were particularly grim on those parts).
