You can't do it by clicking airbase.
I think that Air HQ have this possibility.
You can choose from Regiment to corp.

Kiev Fortress became isolated too!<br/>
<br/>
Sole good news is the end of pestilence.<br/>
Soviets reconnaissance and tank brigades are running in my rear.<br/>

Situation is looking grim.[&:]<br/>

some units became isolated this time.<br/>
<br/>
Losses are horrible (22 regiments disappeared for 20 Russians).<br/>
Only 6.7 K of troopers.<br/>
<br/>
OKW will have to find a solution.<br/>
I receive few units coming back, reinforcement are scarce.<br/>

We will have to fall back.<br/>
This position is under their fleet fire.<br/>

3 Armies are identify and 2 others aren't.<br/>

Air war has been better: 14 vs 68.<br/>

As visible 95 Infantry division has been isolated.<br/>
Four Armies are in first line.<br/>

we are around Gomel and Mozyr.<br/>
I've identify 2 Guard corps.<br/>

The group in the south (isolated one).<br/>
Contain a German reinforced division, few Hungary battalions and Pilfousek brigade (Slovak).<br/>
When this unit is disbanded ...

again a rail to repair following partisan action.<br/>

I had to recover some units before they become isolated.<br/>
A regiment became engaged trying that.<br/>
This explain the visible HQ in second line.<br/>

4 armies are identified there.<br/>
Most dangerous place is in the south, where they try an envelopment.<br/>

Leaving Rumania to keep front line is probably not my best decision.[:(]<br/>
I must find a way to recover most ...

I've no more question about Vitebsk ! It's only a matter of time before it's fall.<br/>
<br/>
Several Panzer divisions are coming to rescue.<br/>
Already 2 regiments are isolated. No hope to rescue them, "hold at all" cost is their order.<br/>

<r> Turn 50. December 10th<br/>
<br/>
along the lake, they didn't try attacks. Only keeping contact.<br/>
<br/>
They took some ground near Pskov.<br/>
As indicated a Cavalry division advance.<br/>
<br/>
2 battalions relieved regiments which were exhausted.<br/>

<t> only way I find to know exact opponent air losses:<br/>
making an airfield attack you can see the % used for the turn.<br/>
For example: already 50 losses indicated. You kill 5 more and total losses go to 60.<br/>
You can tell that you've got half of indicated losses.<br/>
These are only ...

higher view.<br/>
As you can see, they are improving their pushes.<br/>
<br/>
Kiev is under great attacks.<br/>

Air war continue to see our supremacy.<br/>
During entire turn, I loosed 20 planes for 233 to him.<br/>

<br/>
situation seems good before receiving his answer.[&:]<br/>
<br/>
There is a partisan brigade destroying my rail line between Minsk and Borisov.<br/>
His attacks are supported by mass artillery which shattered us.<br/>
I loosed 12 grenadier regiments for only 5 to him.<br ...

<r> Turn 49.<br/>
<br/>
AGN<br/>
They made a major push following the coast.<br/>
I was not really ready for that.<br/>
Situation there is worsening.[:@]<br/>
<br/>
I got 223 Infantry division arriving by rail this turn.<br/>
<br/>

I don't know yet.
Will be function of each other strength.
It may be to gain back what I will loose in first time.
After that who know ?

<t> I don't know yet for entirety. Never get thus far.<br/>
Main problem come from my cautiousness at the beginning.<br/>
Motorized units were poorly used to prevent their losses.<br/>
This authorized Russia to form strong defensive lines with much support.<br/>
Then I loosed shock advantage by ...

<r> AGS<br/>
<br/>
here too, we are suffering.<br/>
<br/>
I've indicated a regiment that has been engaged, trying to retreat.<br/>
They are no more entrench.<br/>
<br/>
During the length of the turn, they loosed about 8.7 K of troopers.<br/>
Already, I must try to think for later.<br/>
<br ...

<r> AGC<br/>
<br/>
I don't know if I will keep Vitebsk?<br/>
<br/>
The unit Red on Grey (8-13) are French Volunteers.<br/>
<br/>
As before, I must replace regiment in great danger by battalions.<br/>
Air war is better; 10 vs 114 during my part for 8 vs 87 during his.<br/>
Total 18 vs 201.<br ...

<r> AGN<br/>

rail line has been repaired<br/>
