Do they mean in total, or since the start of the counter offensive?
This is the original quote:
Less than 10 percent of western-donated equipment has been lost as a result of operations so far,
Sounds to me like it has been since the beginning. But he probably means the heavy equipment.
But this. This would mean Ukraine now has more heavy equipment than at the beginning of the invasion, while Russia stockpile crumbles.
As far as I have followed, Ukraine has lost a lot of the Soviet equipment.
These have now been replaced by Western technologies. In a bit smaller number of pieces. But the quality is much better.
In the German media it is also reported that Ukraine keeps large mechanized brigades (or was it pattalions?) in reserve.
At the moment, they are probably just trying to open a gap somewhere and tie up the enemy in as many sections as possible. And of course, as always, to attack the supplies.
