What's wrong with the PzH 2000 howitzers? DW News ShowDW in Russian
"The howitzers supplied by Germany could not withstand the rate of fire. Howitzers could not withstand the operating conditions in Ukraine..... Howitzers did well in Afghanistan. ... Here in Ukraine, the conditions are different...
neither Germany nor Ukraine were ready for such conditions of exploitation... It will take months, not days, to eliminate the problems..."
"In the middle of the week, Kiev informed the German Defense Ministry that some of the seven PzH 2000 guns delivered at the end of June, after intensive shelling of Russian positions, issued error messages," the publication claims.
