1. Units are losing strength and cohesion with no apparent explanations. For example, my force in Donetsk region has 4 units and one star commander. During period between Late February and Late March, almost two complete units in this stack are depleted (see figure 1). There are some 1.000 men missing and units are without cohesion. The Donetsk stack is not moved or participated in any action during this period and I'm wondering why they are losing men and cohesion? Why only 2 out of 4 units are affected? Also, I haven't received any notification that these units are suffered any weather or supply hits. Desertion or illness? In that case, why there is no message related to specific force? I would very appreciate if someone can explain what happened here.

2. In Late March I have received message that "Soldiers are deserting ranks of the Red Army. We should create more Political commissars". When I click the message Moscow and Yaroslavl are highlighted. Is this just a scripted message unrelated to Ice March scenario or it really affect some of my units? If so, how can I create more commissars?
3. My armored train is able to pass through Novocherkassk and Rostov despite fact that I have zero loyalty and military control in these regions. Enemy also have forces in both regions and cities (through which rail line is passing)! Is this WAD and how this can happen?
4. What is needed for "DF Destroyer squadron" located in Rostov to support Rostov defenders? I have never saw it participates in battle regardless of "bombardment" setting. It just flees to "Mouth of Don".
5. Replacements - Figure above NATO symbol represents number of hits which are missing in elements who use that replacement chit. According to manual we request replacements in terms of replacement chits which is equivalent in strength to an average battalion-sized element. But how many hits does average battalion-sized element has?
Also, may someone explain what represent colors of figures and numbers located above NATO symbol? And what does signify two or three exclamation marks right beside figure numbers (see Figure 2)?

6. New General - In "Ice March" in Reinforce screen (F3) there is option to request "New Red general" It costs 4 EP and I choose it many times but I didn't notice that I actually had received new General. Where is he suppose to appear. Do I get notification in event message box as I have never received such message.
7. Entrenchments - Is there any way to see, at least roughly estimated, value of entrenchment level before attacking specific region? For example if I have Force in Rostov how can I tell, what is entrenchment level of Novocherkassk?
8. Is there possibility to chain up different commands for same force during one turn. For example, can I order Sablin force to go by train to Kamenskaya and disembark (needed: 5 days) and then to move toward neighboring Novocherkassk during same turn (as there is 9 free days after disembarking at Kamenskaya). If I order him to go directly to Novocherkassk by train, disembark and attack will his stack suffer penalty as he entered region by train and not by foot?
Thanks in advance for answers and clarifications.
