U.S. Special Operations Forces were deployed to Grenada beginning on 23 October, before the 25 October invasion. Navy SEALs from SEAL Team 6 and Air Force combat controllers were air-dropped at sea to perform a reconnaissance mission on Point Salines.[54] The helicopter drop went wrong; four SEALs were lost at sea and their bodies never recovered, causing most people to suspect they had drowned.[55] The four SEALs were Machinist Mate 1st Class Kenneth J. Butcher, Quartermaster 1st Class Kevin E. Lundberg, Hull Technician 1st Class Stephen L. Morris, and Senior Chief Engineman Robert R. Schamberger.

UH-60 Blackhawk helicopters delivered SEAL Team 6 operators in the early morning of 25 October to Radio Free Grenada with the purpose of using the radio station for psychological operations.[59] They captured the station unopposed and destroyed the radio transmitter. However, they were attacked by Grenadian forces in cars and an armored personnel carrier (APC), which forced the lightly-armed SEALs to cut open a fence and retreat into the ocean while receiving fire from the APC. The SEALs then reportedly swam to USS Caron.[61] They swam toward the open sea, and were picked up several hours later after being spotted by a reconnaissance plane.[57]

On 25 October, Delta Force and C Company of the 75th Ranger Regiment embarked in UH-60 and MH-6 Little Bird helicopters of Task Force 160 to capture Fort Rupert (now known as Fort George), where they believed the Revolutionary Council leaders lived, and Richmond Hill Prison, where political prisoners were being held. The raid on Richmond Hill Prison lacked vital intelligence, leaving the attackers unaware of the presence of several anti-aircraft guns and steep hilly terrain that left no room for helicopter landings. Anti-aircraft fire wounded passengers and crew and forced one UH-60 helicopter to crash land, causing another helicopter to land next to it to protect the survivors. One pilot was killed, and the Delta Force operators had to be relieved by a Navy Sea King helicopter.[62] The raid on Fort Rupert, however, was successful in capturing several leaders of the People's Revolutionary Government.[63]

The last major special operation was a mission to rescue Governor-General Scoon from his mansion in Saint George, Grenada. The mission departed late at 05:30 on 25 October from Barbados, resulting in the Grenadian forces being already aware of the invasion and they guarded Scoon closely. The SEAL team entered the mansion without opposition, but BTR-60 armored personnel carriers counter-attacked and trapped the SEALs and governor inside. AC-130 gunships, A-7 Corsair strike planes, and AH-1 Cobra attack helicopters were called in to support the besieged SEALs, but they remained trapped for the next 24 hours.

Navy A-7 Corsairs and Marine AH-1 Cobra attack helicopters made airstrikes against Fort Rupert and Fort Frederick. An A-7 raid on Fort Frederick targeting anti-aircraft guns hit a nearby mental hospital, killing 18 civilians.[1]: 62  Two Marine AH-1T Cobras and a UH-60 Blackhawk were shot down in a raid against Fort Frederick, resulting in five casualties.[60]

On the afternoon of 26 October, Rangers of the 2nd Battalion of the 75th Ranger Regiment mounted Marine CH-46 Sea Knight helicopters to launch an air assault on the Grand Anse campus. The campus police offered light resistance before fleeing, wounding one Ranger, and one of the helicopters crashed on approach after its blade hit a palm tree. The Rangers evacuated the 233 American students by CH-53 Sea Stallion helicopters, but the students informed them that there was a third campus with Americans at Prickly Bay.[60] A squad of 11 Rangers were accidentally left behind; they departed on a rubber raft which was picked up by USS Caron at 23:00.[59]
