"We will temporarily stage one armored brigade combat team's vehicles and associated equipment in countries in central and Eastern Europe," Carter told the press in Tallinn on Tuesday.
"This pre-positioning… includes tanks, infantry fighting vehicles and artillery."
"Estonia as well as Lithuania, Latvia, Bulgaria, Romania and Poland have agreed to host company-to-battalion-sized elements of this equipment which will be moved around the region for training and exercises," said Carter.
Earlier this month, responding to reports on US preparations to station heavy weapons for as many as 5,000 American troops in Baltic and eastern European countries, Russian Defense Ministry official Yuri Yakubov said such a move would represent:
"The most aggressive step from the Pentagon and NATO since the Cold War."
"If heavy military weapons such as tanks, artillery batteries and other weaponry really does appear in countries in eastern Europe and the Baltics," warned Yakubov, "Russia will have no option but to strengthen its forces and resources on the Western strategic front."
