NBC News took a look at the facts behind each candidate's claims — from who supported which military interventions over the last decade to reforming the Department of Veterans Affairs. Here's how they stacked up to the facts:

In Wednesday night's NBC News Commander-in-Chief forum, both candidates offered up a series of inaccuracies and half-truths to national security questions.

Democratic presidential nominee Hillary Clinton speaks during a veterans forum at the air and space museum aboard the aircraft carrier USS Intrepid on September 7, 2016 in New York, New York.

CLINTON CLAIM: "Classified material has a header — top secret, secret, confidential — and nothing, I will repeat, this is verified in the report by Department Of Justice, none of the emails sent or received by me had that header," Clinton said.

THE FACTS: Header aside, Clinton is dodging the question. According to the FBI Director James Comey, his agency found that 110 emails in 52 email chains contained classified information at the time they were sent or received. Another 2,000 emails were later "up-classified" to make them confidential after the time they were sent, Comey added.



CLINTON CLAIM: "I took it very seriously," Clinton said during the forum highlighting her use of a separate server for classified information and other precautions she took to protect national security. "I did exactly what I should have done, and I take it very seriously."



THE FACTS: Comey disagrees.



"Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information," he said of his review of her.

CLINTON CLAIM: "There is no evidence my system was hacked," she said of her private email server.

FACTS: True, as the FBI said it's unlikely hackers would leave such evidence.



Comey said the FBI "did not find direct evidence" because it's "unlikely" that it would be possible to "see such direct evidence." Comey added that the FBI did "assess that hostile actors gained access" to email accounts that Clinton communicated with via email.



"Given that combination of factors, we assess it is possible that hostile actors gained access to Secretary Clinton's personal e-mail account," Comey said.



CLINTON CLAIM: "With respect to Libya, there's no difference between my opponent and myself."



THE FACTS: Back in 2011, Trump and Clinton were on the same page — Trump recorded a video supporting the kind of intervention Clinton advocated while Secretary of State — but Trump later tried to rewrite his past statements in a February debate by insisting he "never discussed that subject" and that "we would be so much better off if Gadhafi were in charge right now."



Later, Trump acknowledged his past support and said he didn't like the results. "I was for something, but I wasn't for what we have right now," he said.



CLINTON CLAIM [ON IRAQ WAR]: "He supported it. He told Howard Stern he supported it. So he supported it before it happened, he supported it as it was happening and he is on record as supporting it after it happened."

THE FACTS: She's technically correct — Trump supported the war before, and 48 hours after the invasion although he began questioning it within a week and has been steadfast in his opposition since.



"Yeah, I guess so," Trump said in a 2002 Howard Stern interview. "I wish the first time [the first Gulf War] it was done correctly."



He reiterated this support two days after the invasion on March 21, 2003, saying that it "looks like a tremendous success from a military standpoint."



But six days after the invasion, he told the Washington Post that he thought the war was "a mess."
