Pentagon plans call for "wheeled vehicles only, no tanks", as they would tear up city roads.
The memo, with Thursday's date, says its objective is to "provide initial guidance for the planning and execution" of a procession that would run from the White House to the Capitol and integrate with the city's annual Veterans Day parade.
Military parades are not common in the U.S. and are usually held to celebrate war victories.
White House budget director Mick Mulvaney has also estimated the display could cost upward of $30 million.
Military parade will be held on the instruction of President Donald Trump who had directed Pentagon to hold a large-scale military parade to contributions of veterans throughout the history of the United States military, starting from the Revolutionary War and the War of 1812 to today. Older aircraft will be included as available.
Other guidance show the parade will be integrated with the annual Veterans Day parade in Washington, D.C. and follow a route from the White House to the U.S. Capitol.
The Joint Staff will be responsible for planning, while the Northern Command will carry out the execution.
One major element that will be missing from the festivities: tanks.
The memo, dated Thursday, indicated "a list of planning considerations" from Secretary of Defense James Mattis.
"We'll see if we can do it at a reasonable cost, and if we can't, we won't do it, but the generals would love to do it, I can tell you, and so would I", Mr. Trump said last month. Trump has sought a military-style parade since attending a Bastille Day parade in Paris with French Prime Minister Emmanuel Macron. The preliminary plan calls for Trump to be surrounded by Medal of Honor recipients and veterans in a viewing area.
