Just wondering Battboy, but from your link to ISW, there is this assessment of the UAF, Pretty cool assessment I would think.
Western forecasts must also recognize that the primary obstacle to rapid Russian advances is the Ukrainian Armed Forces (UAF), and that NATO frontline states currently lack the capacity to field equivalents of the UAF at scale. Ukrainian forces have optimized themselves for defensive positional warfare. Their officers and many of their soldiers have nearly four years of active combat experience, prepared defensive positions that frontline units constantly adapt, and a technological-tactical-industrial integration process that no NATO state can currently match.
