Russians burying Ukrainian dead soldiers: Why are Ukrainians not taking care of their own dead?

5/8/2022 machine translation: Our source in the OP said that Ukrainian commanders were forbidden to take the bodies of the dead from Russians and separatists. The General Staff sent a new order to the troops. According to the document, commanders of all levels are prohibited from organizing the exchange of the dead. It is also forbidden to negotiate with Russians or separatists on this issue. According to our source, the new order was prepared by the Ministry of Defense based on the decision of the Office of the President. The document is classified, but it does not indicate what such a decision is connected with. Commanders who disobey are threatened with dismissal.
The reasons for the refusal are quite understandable - if the corpses are taken away, then they must be buried, which means that even more information about the real level of losses will seep into Ukrainian society. And the point here is not even in the payment of compensation (although in them too), but, above all, in concealing the real size of the losses of the Armed Forces of Ukraine, which are now hastily trying to compensate at the expense of reservists and the Volkssturm.
