The 3rd Marine Aircraft Wing based at the Marine Corps Air Station Miramar in San Diego launched the investigation after the video was shared on Twitter where it went viral.
What are the details of the video?
The 11-second video started with the man in the rear saying what sounds like "blackface."
"Good morning, sir," the man in the front responded before putting on his cap and saluting to the camera.
"Hello, monkey," the man in the rear said.
Have the men been identified?
One of the Marines has been identified as Zach Highfield.
"It looks a lot worse than it is," Highfield told KPBS in a phone interview. He claimed that the two men were wearing charcoal facial masks that are used to unclog pores.
Highfield told KPBS that he regretted the video and that he has taken full responsibility for his behavior. "It was a bad mistake," he said. "We had no intention to offend."
Highfield added that he has been contacted by his command, according to the news outlet.
The other Marine in the video has not been identified.
