Poland has sought to entice Trump into bolstering USA commitment to the country's defense, including by appealing to the President's ego, even floating the notion of naming the base for United States troops "Fort Trump".
The formal announcement is expected on Wednesday afternoon, when President Donald Trump greets Polish President Andrzej Duda at the White House.
The deployment follows months of lobbying from Warsaw.
"They're going to put on a very small show for us and we're doing that because Poland has ordered 32 or 35 brand new F-35s at the highest level", Trump said.
Though details about the troop movement in Europe remain unclear, Trump has criticized Germany for missing a North Atlantic Treaty Organisation spending benchmark that calls for dedicating 2% of gross domestic product to defense.
The additional troops will be sent to "enhance mutual interoperability" of the two countries' militaries, the unnamed administration official said on Tuesday.
"I congratulate you on that (purchase)", Trump told Duda.
"We are protecting Germany from Russian Federation and Russia is getting billions and billions (of dollars)", Trump said. Eastern European nations have reached out to the USA and North Atlantic Treaty Organisation for greater protection, worrying that they might be the next target of Russia's military advance.More news: OnePlus 7 Pro gets Almond color option

Trump said Poland is interested in buying more than 30 F-35 Joint Strike Fighter jets from the U.S.
The U.S.is also helping to construct a missile defense base in Poland, which aims to defend U.S. and European allies from a "rogue" missile threat, namely Iran.
"Moments ago we witnessed that impressive flyover of this cutting edge, F-35 as it flew over the White House", the president said. While the press conference focused on areas of agreement, Trump said he differed with Poland's efforts to force the country's Supreme Court justices to retire early.
Polish Counsel General Maciej Golubiewski said told MSNBC this morning that the agreement "quantitatively and qualitatively" increases US troop presence in the country.
A joint combat center would also be set up. Still, the USA has been loath to escalate tensions with Russian Federation by making a move that Moscow would no doubt see as a direct threat.
Trump also highlighted Poland's need for energy independence without specifying that it is Russian Federation in particular which dominates much of Europe's energy market.
The United States already has troops in Poland as part of a 2016 agreement with the North Atlantic Treaty Organisation military alliance in response to Moscow's annexation of Crimea from Poland's eastern neighbor Ukraine in 2014. "And it's unfortunate", Trump said. You know, they get hurt, unfortunately, too often.
