A Southern California high school teacher who was caught on camera denigrating the intelligence of people serving in the US military to his students has been fired.

On Tuesday evening, the Unified School District made a unanimous decision to fired El Rancho High School history teacher Gregory Salicdo, 49, reported the Los Angeles Times.

'His comments do not reflect what we stand for, who we are,' said Board of Education President Aurora Villon.

'The classroom should never be a place where students feel that they are picked at, bullied, intimidated.'

The video was stealthily recorded in class in January by a 17-year-old high school senior, identified by KTLA as Victor Quinonez.

In the clip, Salcido can be heard making a variety of unflattering remarks about service people, at one point calling them the 'lowest of the low'.

The videos went viral after being posted on Facebook by a Connecticut woman claiming to be a friend of the mother of the student who recorded the clip

Although the videos - shot from under a desk - do not show Salcido's face, El Rancho High officials confirmed to The Orange County Register that the person speaking in the video is in fact Salcido and that the video was shot in a school classroom.

In one of the clips, Salcido can be heard saying: 'Think about the people who you know are over there. Your freakin' stupid Uncle Louie or whatever. They're dumb s***ts. They're not like high-level thinkers. They're not academic people. They're not intellectual people.'

He then says that overseas service people are 'the freakin' lowest of our low. Not morally - I'm not saying they make bad moral decisions - they're not talented people.'

As he speaks, students can be heard laughing in the background.

The rant seems to have been sparked in reaction to Quinonez, who was wearing Marines shirt.

The videos went viral after being posted on Facebook by a Connecticut woman claiming to be a friend of Quinonez's mother.

'My friends [sic] son was sporting his marine sweater while this liberal douche teacher rants about the military,' Kimberlie Flauto wrote on Facebook on Friday, while exhorting people to 'help me make this go viral.'

Salcido has allegedly had previous issues with students.

He was placed on paid administrative leave after police received a complaint that he had hit a student in 2012.
