Four military heroes reminisced about war and why they served in "Modern Warriors," a Fox News Channel special in honor of Veterans Day.

Retired Army Ranger Sean Parnell, retired Navy SEALs Rob O’Neill and Marcus Luttrell, and Medal of Honor recipient Dakota Meyer joined Fox & Friends co-host and Army veteran Pete Hegseth to trade riveting stories of combat and brotherhood on the battlefield.

Meyer, a Marine veteran of the war in Afghanistan, recalled speaking with his teammates before battle about going home and what they would eat later that night.

"Eight hours later, I'm putting my entire team in a bodybag and sending them home and I've lost everything. That's how fast it goes. You never expect it, it just happens," he said.

O'Neill, who fired the shots that killed terrorist leader Usama bin Laden in 2011, said that although trading gunfire on the battlefield is different every time, it shouldn't be.

"Complacency kills and complacency is caused by success and if you do something right 400 times, that 401st time, it's gonna get you," he said.

He added that there's "no worse feeling" than realizing an enemy's bullets can reach you without retribution.

"You might as well not even shoot back until we can get on a level playing ground," O'Neill said.
