On the southern and northern sectors of the battle-line the Ukrainian forces have been thinned out and are only able to defend against minor forces.I count the equivalent of some 27 brigade size formations in that area. The usual size of a brigade is some 3,000 to 4,000 men with hundreds of all kinds of vehicles. If all brigades had their full strength that force would count as 97,500 men. In a recent interview the Ukrainian military commander Zaluzhny said that his army has 200,000 men trained to fight with 500,000 more having other functions or currently being trained. The forces which are currently getting mauled in the Bakhmut area constitute 50% of Ukraine's battle ready forces.
