1. Excuses or not, ULTIMATELY any incident out of the ordinary performance should be INVESTIGATED, not to fault find or play blame games, but to CORRECT errors, thru needed or better training from the production and quality control stage, to operator DAILY usage, which is what testing and rehearsals are meant for, to be prepared and ready for the real event, in peace or in war, as NO mortal is perfect, so too man-made creations, so that better performance and productivity can be achieved to progress.
2. There is nothing to hide, as once evidences are shown, excuses are only useless as only truths can set us free.
3. While the Leopard tank was made in Germany, and touted, tested as one of the best tanks ever in this century, ultimately, no machine is perfect, more so with the needed foreign labor by the Millions displaced recently by Middle Eastern wars that kind Germany had taken in and provided homes, education, training and employment for them in various industries and supply chains for them to put food on their tables for themselves and loved ones, and even contribute to German Civilization, even as the few radicalized migrants had been ungrateful and attempted to create problems for the elevated German Civilization as well as in EU.
German industries had long been touted and accepted as the best, none would deny, more so their mercedez of the 1980s with square headlights - the very last full model that was built under German hands in Germany that amazingly still works well today and considered a classic car, but sadly lost its competitiveness when more such newer models of branded luxury cars were made in China, and perhaps may had been compromised by such new workers whom are non Germans whom had for centuries been admired for their values in attention to details, intelligence, skills, hardwork, thrift, etc...something that was built up over centuries thru education and life experiences, which can never be learnt overnite or in months...
Such evidences lays in the many Leopard tanks that Germany had kindly sent to assist the Ukraine, but only just in weeks, to see most them being destroyed and abandoned..... Thus questions abound as such battlefield equipment are seldom towed back or allowed for investigations as none would do so under battlefield conditions......
