Lt. General Mike Flynn is backing Donald Trump's assertion that military generals have been 'reduced to rubble' under President Obama – and cited himself and fired Gen. Stanley McChrystal among those moved out over 'disagreements.'

'There is a severe disconnect between this White House and frankly the president and our military,' Flynn told 'Fox and Friends' on Thursday.

'I mean there’s a lot of frustration within the ranks and there’s a lot of frustration, I know, in the senior leadership. You look over the past eight years of generals that have been moved out of the service for disagreements or just the lack of being able to push a particular strategy that we know that can lead us to victory,' Flynn said.

Asked by host Steve Doocy to 'give us some names,' Flynn – who Trump considered as a running mate – mentioned retired Gens. David McKiernen, Stanley McChrystal, James Mattis – and himself.

'There are others,' he said.

Retired Lt. Gen. Michael Flynn, is backing Donald Trump's assertion that military generals have been turned to 'rubble' under President Obama

Flynn was asked about the issue after GOP nominee Donald Trump said at a 'commander in chief forum' on NBC Wednesday blasted 'embarasing' leadership under President Obama.

'I think under the leadership of Barack Obama and Hillary Clinton the generals have been reduced to rubble – they have been reduced to a point where it’s embarrassing for our country,' Trump said.

Trump on Wednesday said he would ask generals to produce a plan to defeat ISIS within 30 days of taking office – after saying he already had a plan and earlier saying he knew more about ISIS than the generals.

'If like maybe a combination of my plan and the generals’ plan – or the generals plan. If I like their plan, Matt I’m not going to call you up and say, "Matt we have a great plan." This is what Obama does,' Trump said.

Hillary Clinton hit back at Trump on Thursday, telling reporters he 'trash-talked American generals.'

Trump and Clinton have been engaged in a battle of brass, after Trump rolled out 88 generals and admirals supporting him, and Clinton countered the following day with 95 flag officers who support her.

The Clinton camp said she got more brass than any recent non-incumbent Democrat, whereas Trump was 400 behind 2012 GOP nominee Mitt Romney.

Flynn has said he got pushed out after questioning Obama's strategy to defeat ISIS.

McChrystal resigned after publication of a Rolling Stone magazine feature about him called 'The Runaway General' where McChrystal and his staff were quoted speaking derisively about top civilian leaders.

The Clinton camp hit back at Trump following Wednesday's forum.

'Trump's unpresidential trifecta tonight: 1. Attack our generals 2. Praise Putin 3. Blame women in combat for sexual assault,' tweeted Clinton spokesman Brian Fallon.

'Trump thinks our nation's military leaders are contestants on The Apprentice,' Fallon said in another tweet.

Former House speaker Newt Gingrich, another Romney supporter, blasted Romney in his own appearance, after the former Massachusetts governor sent out a tweet saying third party candidates should get to participate in debates.

'I feel sad for Mitt Romney,' Gingrich said. 'This is a guy who for a long time in Massachusetts claimed to not really be a Republican …He said he wasn’t for Bush and Reagan in the 1980s,' then became the GOP nominee for a 'brief shining moment.'
