First thanks for getting the demo

The game looks very promising:
Though I have a qouple of questions/notations:
1)The Icon seize is getting smaler in the distance. I find it very small when the unit is far away. Is there a function to log the size of it?
For a listing of hotkeys press the 'k'. The key for increasing unit size i the ' key. You reduce them back to normal using the / key.
2) When I want to give my units the hold fire order using the leader the attached unit dont adopt the orders (like using any move order).
If you want to be sure that the squads in a platoon all adopt a sub-order, then hold down the SHIFT key when issuing the order to the CO unit. The reason the sub units didn't switch to 'Hold Fire' was because they already had the Defend (probably Defend --> Stay) base order before you gave the CO unit the Defend --> Hold Fire order. Sub units only follow the CO order when it's a DIFFERENT BASE order from what they had. The key is the Different Base order not just different order.
3)I cant use the facing order for my infantry men.
Were they mounted on vehicles or buildings? you can not issue facing orders from mounted units.
4)Can the enemy spotted by sound.
You may be able to hear enemy tanks coming, but your units cant spot or target based on sound they hear.
5)longer news about the units are not very good to read because of the scroll up and scroll down buttons
You can also use the scroll key to scroll through the message log. Also you can enlarge the message log using the F6 key, and the F5 decreases it (only down to original size), F7 toggles it off and on.
6)I have to click every unit to see which unit can see the enemy.
Yes, though with the correct base order, units will sight and target enemy units without you selecting designating their targets. But only if they have the appropriate Base order, such as Defend, or Engage --> Hold.
I hope that makes it a little easier to play!
thanks
