Amphibious vehicles for NATO water crossings

Do NATO armies need more vehicles able to cross rivers and lakes under their own power?

Yes; self-swimming combat vehicles reduce dependence on bridges, while modern equivalents of the DUKW would address an especially important logistics gap.

Independent swimming capability creates more routes and makes an opponent's denial problem harder, even if it is not always the preferred way to move. Logistics vehicles comparable to the World War II DUKW may matter even more because supplies must keep flowing after the first crossing.
