WASHINGTON (REUTERS) - The Pentagon is poised to store battle tanks, infantry fighting vehicles and other heavy weapons for as many as 5,000 troops in several Baltic and Eastern European countries, to deter any possible further Russian aggression in Europe, the New York Times reported on Saturday.

Citing US and allied officials, the newspaper said that if approved the proposal would mark the first time since the Cold War that Washington has stationed heavy military equipment in the newer Nato member states in Eastern Europe that were once part of the Soviet sphere of influence.

The proposal, which seeks to reassure European allies in the wake of Russia's annexation of Ukraine's Crimea in March 2014, is expected to be approved by US Defence Secretary Ash Carter and the White House before a Nato defence ministers' meeting in Brussels this month, the paper said, quoting senior officials.

Asked about the article, a Pentagon spokesman said no decision had been made about the equipment.

"Over the last few years, the United States military has increased the prepositioning of equipment for training and exercises with our Nato Allies and Partners," Colonel Steve Warren said in a statement.

"The US military continues to review the best location to store these materials in consultation with our allies. At this time, we have made no decision about if or when to move to this equipment," he said.

The Times said that as it stood now, the proposal envisaged that "a company's worth of equipment - enough for about 150 soldiers - would be stored in each of the three Baltic nations: Lithuania, Latvia and Estonia. Enough for a company or possibly a battalion - about 750 soldiers - would be located in Poland, Romania, Bulgaria and possibly Hungary."
