There is no place to repair Ukrainian equipment; it has to be taken to Poland
Ukraine has big problems with repairing military equipment, which gets damaged and simply breaks down.
Military expert Oleg Starikov stated this on air during a video blog broadcast by Ukrainian propagandist Ruslan Bizyaev, reports a PolitNavigator correspondent.

According to Starikov, due to the successful actions of the Russian military, which destroyed repair factories, the equipment will have to be exported abroad.
“Now we have one of the problems that I spoke about - the restoration of damaged military equipment. That is, the so-called rebate. We have rebates for old equipment, but not for new ones.
On the other hand, tank repair plants, all repair plants that repaired equipment for both the Air Force and the Ground Forces, were destroyed by missiles of the Armed Forces of the Russian Federation.
Therefore, equipment that is on the battlefield is taken out. For two, three or four months they didn’t know what to do with it, then Ramstein decided that it was necessary to create repair units, they were created in Germany and Poland, our equipment was taken there, repaired and delivered,” Starikov said.
There's nowhere to repair Ukrainian equipment, so it has to be shipped to Poland.
