Paul Rieckhoff of the Iraq & Afghanistan Veterans of America, tweeted: "Who is really surprised by this?"
Analysts say the comments could prove damaging with the president needing support from military voters as he bids for re-election.
What is Trump reported to have said?
According to The Atlantic, Mr Trump cancelled a visit to a US cemetery outside Paris in 2018 because he said it was "filled with losers".
Four sources told the magazine he rejected the idea of visiting because the rain would dishevel his hair, and he did not believe it important to honour America's war dead.
During the same trip, the president also allegedly referred to 1,800 US soldiers who died at Belleau Wood as "suckers". The battle helped to prevent a German advance on Paris during World War One and is venerated by the US Marine Corps.
On top of the comments from veterans, President Trump's challenger in November's presidential election, Joe Biden, responded by saying his rival was "unfit" to lead.
"If the article is true - and it appears to be, based on other things he's said - it is absolutely damning. It is a disgrace."

Democratic Senator Tammy Duckworth, a veteran who lost both legs while serving in Iraq, said President Trump "liked to use the US military for his own ego".
He said: "When Donald Trump calls anyone who places their lives in service of others a loser, we understand Trump's soul."
How is the White House fighting the story?
President Trump has pushed back hard against the reports, calling them "fake news".
"To think that I would make statements negative to our military and our fallen heroes when nobody's done what I've done with the budgets, with the military budgets, with getting pay raises for our military," he said. "It is a disgraceful situation by a magazine that's a terrible magazine."
Speaking to reporters on Friday, he suggested the source of the story was his former White House chief of staff, John Kelly. Mr Trump said the former US Marine general "was unable to handle the pressure of this job".
Secretary of State Mike Pompeo told Fox News on Friday morning he was with the president for a good part of the trip to France and never heard him use the words described in the article.
Defense Secretary Mark Esper was quoted by Politico as saying Mr Trump had "the highest respect and admiration for our nation's military members, veterans and families", though the Pentagon chief did not explicitly deny the story.
Another former White House chief of staff, Mick Mulvaney, and former press secretary Sarah Huckabee Sanders were among those in Mr Trump's orbit who rejected the story as false.
Where do Trump and the US military stand?
The US president has often staked claim to strong support among the military, and Pew Research Center last year found that veterans were generally supportive of him as commander-in-chief, with 57% in favour. Three-fifths of the veterans identified as Republican, the research found.
But there have been previous spats and controversies.
He caused outrage by saying the late Senator John McCain, a prisoner of war in Vietnam, was not a "war hero" saying: "I like people who weren't captured."
President Trump has never served in uniform. He received five deferments from a military draft during the Vietnam War - four for academic reasons and one for bone spurs, a calcium build-up in the heels.
