At 3:00 a.m. Tuesday, an unspecified SEAL team approached the Port of Miami from Biscayne Bay on a Combatant Craft Medium, also called a stealth boat, a multi-mission tactical craft built to infiltrate and exfiltrate Special Operation Forces and conduct special reconnaissance operations. It delivered the SEALs to the southeast tip of Dodge Island, and they crept stealthily toward the target, navigating through the labyrinth of shipping containers that dotted the island like rows of dominoes. Having reached the building undetected, the SEALs split into four-man teams and began looking for guards and anti-intrusion devices that might alert someone to their presence.
