This claim is akin to stories of lack of plumbing in Russia, based on language barriers and ignorance of the audience.
First, I am sure that more than 19 HIMARS are destroyed to date, but at the time your expample relates to the report of the military spoken Konashenkov who once claimed 19 HIMARS launches intercepted. It was then mistranslated and turned into your mem.
Your posts are suspect as well.
