What does it take to be a Navy SEAL like the heroes who took out Osama bin Laden?
Boyd's instructors are former Navy SEALs who run the "Extreme SEAL Experience" outside Norfolk, Virginia, the home base for the elite of the elite, SEAL Team 6.
Training started at 5 a.m. Chief instructor Don Shipley immediately ordered Boyd to drop and give him ten pushups.
SEALs run everywhere, there's no walking. Boyd quickly changed into boots and camouflage fatigues.
First came the punishing exercises that were only a warm-up for the day ahead of jumping jacks, leg lifts, and crawling on your belly.
Boyd's face was painted in camouflage: "Every part of my body needs to become invisible," he explained.
The ability to operate undetected is a crucial element in the transformation into a Navy SEAL.
Next came weapons training from instructor Lyle Roberti who showed Boyd the main weapon for a Navy SEAL, the M4 carbine assault rifle.
"There's a 100 percent chance this is the weapon that killed Osama bin Laden," said Roberti.
SEALs are proficient with all kinds of weapons. Boyd was taught the double-tap technique, which is two quick kill shots with a pistol.
As rain fell, Boyd learned sniper training, lying flat on the ground and blasting a target with a powerful 50 caliber rifle.
"Target practice on the ground is one thing, but shooting from a moving helicopter is something else. I managed to hit the target with my M4 carbine. I couldn't hit a thing with a shotgun," Boyd said.
Then came the biggest test of all, when the chopper zoomed into position over a river, Boyd had to jump 25 feet into the water: "My heart was pounding as I made the jump."
This is how a Navy SEAL tests his limits, more pain, more exercises: "I felt like I was drowning as I was hosed down while rolling in the mud. Then it was back into the water and more running until my legs felt like rubber," said Boyd.
Finally, just when he thought it would never end, Boyd's training was over: "After a day like this, you have total appreciation for these American heroes, the Navy SEALs."
