UK military officials have expressed surprise at the absence of advanced Russian military technology, such as the T-14 Armata tank and Su-57 fighter jets, on the Ukrainian battlefield. Major Maguire highlighted that instead of deploying these high-profile assets, Russia has relied on older models, facing challenges in production exacerbated by international sanctions. Concerns over reputational damage and the operational readiness of advanced equipment have led to this strategic choice, while NATO forces remain confident in their ability to neutralize any advanced systems Russia may possess. The overall performance of the Russian military has not met expectations, indicating a decline in effectiveness as the conflict in Ukraine continues.
