“Russian forces now appear to be “reposturing” for an assault on the capital.
To cut the city off from any reinforcements that will undoubtedly rush north if the capital is threatened will be an enormous undertaking.
Given that the city measures roughly 35km (22 miles) north to south and 25km (16 miles) east to west, Russia will need to establish a cordon of at least 90km (56 miles).
A tall order
With each Russian battalion tactical group able to defend a frontage of about 1km (0.6 miles), this is a tall order.
Without calling up reserves from the homeland, this task is probably beyond the capability of the forces Russia has deployed into Ukraine.
Russia could have about 50,000-100,000 troops around Kyiv. It took 2.5 million to capture Berlin in 1945, with heavy losses.”
