What makes Ukraine’s defence tech export unique ?

Apparently, Ukraine’s defence technology exports have something truly unique about them, and I’m trying to understand what sets them apart from other countries. I recently came across references to their rapidly growing industry, but I wonder what specific factors make their defence tech attractive on the global market. Has anyone encountered details on what distinguishes these products beyond just being high-tech? Also, what role might investment play in supporting this sector’s uniqueness? I’m especially interested because I’ve been watching the impact of these exports on Ukraine’s economy and international partnerships, and it seems like there’s more than just technology involved. Does the feedback loop from combat conditions contribute to their uniqueness? Any personal stories or observations about how this export sector operates would be really helpful.
