John R. Deni in War On The Rocks recommends a return to a more permanently forward-stationed army.
[With] specific regard to Europe, the Pentagon should aim to station these units in Poland, either in whole or in part through split-basing. Stationing in Poland would provide greater assurance to Eastern Europe and more effectively deter aggression. Most importantly from a fiscal perspective, the Polish government has evinced a willingness to share some of the costs of construction and base operations.
According to Deni there are pretty much only advantages to having forward-stationed troops instead of relying on a scheme of rotational deployment.
