From the world’s rivers and oceans Navy Seals attack America’s enemies. You won’t see them coming. Don’t even try to catch them. Seals are at home at sea, on land and in the air. They strike without warning using 1)demolition charges, overwhelming firepower and sophisticated 2)suppressed weapons. 美国海军海豹突击队从世界各大河流与海洋攻击美国的敌人。你根本来不及看清楚他们什么时候来，也别想抓到他们。不管在海上、陆地上还是空中，海豹突击队都如鱼得水。他们毫无预警地先发制人，靠的是爆破，优势的火力以及精巧的消音枪。
Kevin Dockery(Writer): They are among the best trigger-pullers in the world. 凯文·多克里（作家）：他们是世界上一等一的快枪手。
Seals have a reputation for being the meanest strike force on the block. They take on some of the most dangerous and secretive missions in the military playbook. If regular 3)infantry formations are 4)blunt instruments, then Seals operate as small, surgical strike teams; always outnumbered, but never outgunned. Seals even up the odds by becoming masters of 5)stealth.
The Seals’ primary theaters of operation are rivers and oceans. For the Seals, water is home. They use it to their advantage for 6)concealing 7)infiltration and extraction. The Seals’ water-borne missions are an inheritance from their ancestors, a small group of navy swimmers who formed the underwater demolition teams.
Dockery: There is one direct line of ancestors to today’s Navy Seals. Every Seal, who has ever been, owes his existence to the underwater demolition teams.
The underwater demolition teams were organized after one of the costliest invasions of the Pacific war—the assault of Tarawa in November, 1943.
Dockery: …where the U.S. Marines lost more men due to drowning before they ever reached the beach. Why did they lose so many men? They didn’t know how deep the water was. They didn’t know where the coral heads were. They didn’t know where the obstacles were.
The high price paid in blood at Tarawa 8)galvanized senior navy officers into action.
Dockery: Admiral Richmond Kelly Turner, who had planned the operation at Tarawa, swore that he would not see that happen again. He looked for the men who could examine the beaches. He looked for men who could go into the water and find the obstacles.
Admiral Turner found these men and an elite Navy team trained in the use of explosive charges. They were called Navy Combat Demolition Units.
On 9)D-Day in June, 1944, NCDU teams landed on the Normandy beaches. Under heavy fire they set off demolition charges, blowing up obstacles that weighed tons. From the ranks of these men, who would become D-Day heroes, Admiral Turner recruited the Navy’s new underwater demolition teams, or UDTs.
Operating on rivers and at sea is an essential mission for the Seals. Larger 10)amphibious assault forces attack beaches head on in massed formations. Seals need to slip in unnoticed and avoid a 11)showdown on the shoreline. They insert and extract using discreet surface and submerged craft that guarantee them a low profile.
Airborne insertion is an essential part of the Seals’ playbook for getting men and materials on the ground quickly.
Dockery: In the name of the Seals, there are three environments—sea, air, land. One of the most difficult environments in that name is air. That means these are Seals who jump out of planes and fly down on a parachute.
The Seals are the most formidable Naval Special Operations Force in existence. Their awesome firepower, airborne insertion techniques and stealthy underwater vehicles give them the edge against even the most determined opponents. The U.S. Navy Seals; the toughest, stealthiest special operations force in the world.
