Russia promotes conventional forces in new doctrine, President Vladimir Putin of Russia has signed a revised version of the country's military doctrine, which identifies major threats to security.
The new document promotes the use of Russia's conventional, non-nuclear forces as a deterrent.
Chief among new threats identified by planners are the armed conflict in neighbouring Ukraine as well as events in the Middle East and Afghanistan.
Russian forces are believed to be operating covertly in eastern Ukraine.
Their reported intervention on the rebel side, as well as the annexation of Crimea from Ukraine in March after a disputed referendum, has been met with economic sanctions by Western states.
Russia's air force has also stepped up patrolling in international airspace close to Nato states while the Russian navy has raised its international profile to a lesser extent.
'Indirect action'
Nato expansion into eastern Europe remains the main military threat identified in the new planning document, published (in Russian) on the Kremlin website, which replaces the 2010 doctrine.
Ukraine's parliament voted this week to drop the country's non-aligned status and work towards Nato membership. However, its prospect of actually joining the alliance is questionable, given its territorial dispute with Russia over Crimea and the continuing conflict in its eastern regions.
After a meeting last week, the Russian Security Council announced in a statement (in Russian) that the new doctrine would take account of "the emergence of new threats for Russia, which became evident in the situation in Ukraine and around it and the events in Northern Africa, Syria, Iraq and Afghanistan".
Notwithstanding that Russia has itself been accused by Nato regularly of covert military deployments in eastern Ukraine, the Security Council also found that unnamed "leading states" were taking "indirect action" to advance their interests.
They were, it said, using "the population's potential for protest, radical and extremist organisations, and private military companies".
America has long been accused by Russian hawks of steering pro-democracy uprisings in Ukraine and other ex-Soviet states to further its interests.
The doctrine remains defensive in nature, the Russian Security Council stressed, and regards use of military force only as a last resort.
As well as possessing a nuclear arsenal to rival that of the US, Russia maintains one of the largest conventional armies in the world, numbering just over 766,000 active officers and soldiers as of last year, compared to America's 1,370,000.
