I consider the blog of "Colonel Cassad" the best informed and most honest blog about the situation in the Ukraine, bar none. Right now, he is reporting that while there is an increase in the combat operation, this is more a case of "combat reconnaissance" (opening fire to try to evaluate the enemy disposition) then of a real full-scale attack.
That is the good news.
The bad news is that a energetic "combat reconnaissance" is exactly what the Ukies would be doing before a major offensive.
Please don't panic, I will try to keep you posted. Right now, this is not a full scale attack. Not yet.
