Directly from the horse's mouth...
A curious, a report written by Valentin Nalivaychenko, the head of Ukraine's secret service (the SBU), and addressed to the President of Ukraine, Petro Poroshenko, detailing mass desertion from Ukrainian army. I found it here.
And here is my translation, I have focused on translating only the main text:
I report that...
...in the period between 14 to 19 July 2014 we are observing a catastrophic rise (to 47% that is 3473 people) in the number of deserters from the Armed Forces and National Guard of the Ukraine in comparison with the same data from only a week before (25%, that is 1847).
Besides that, the number of those that went missing has risen (to 47%, that is 1344 people, last week: 344, that is 10%).
This phenomenon is linked to the increased activity of the enemy in the Donetsk and Lugansk regions, and the increase in casualties of the abovementioned forces. This fact influences the combat capability of the manpower, and makes the continuation of the Anti-terrorist Operation (ATO) impossible. In case this negative dynamic continues, within 2-5 days, 2 thirds of battle-worthy units taking part in the ATO will cease existing.
In the interests of maintaining the capability of armed forces, I suggest conducting a withdrawal to the area of Dobropol'e and Smolyaninovo. After restocking ammunition, regrouping, and rotation of 60% of the troops, offensive shall continue.
While the head of the secret service complains about soldiers losing their will to fight, the Finance Minister, Oleksandr Shlapak, complained that the state is running out of money to fund the war.
