Another good comment.

The operational strategy and tactics used in Crimea depended to a large degree on the presence of a Russian base and others factors. Forces in the Southern Military District were on heightened alert and readiness because of the Sochi Winter Olympics. Russian forces were able to operate in a friendly, largely Russian-speaking environment, and Moscow knew, probably in great detail, the disheveled condition of the Ukrainian Armed Forces.

In this sense the operation could be difficult to replicate elsewhere, even if the political will exists in Moscow to attempt some economically unsustainable policy of land grabbing from neighbors. For example, the self-proclaimed Transdnestr republic is effectively cut off from a Russian military perspective, meaning it would be much more difficult to accomplish such an operation and largely depend on insertion by air. The same problems would be encountered in the Baltic states, but they have nothing to fear because Putin would never attack a NATO member.
