Did President Reagan send any Navy SEALs to Libya to fight?

Answer 1

There is no public record of the SEAL's being engaged in the Libya operation, and it's unlikely they would've been used since the Libyans had no real Naval or Air threat that the U.S. was concerned with. Most of the recon was done by satellite and the actual bombing and limited encounters were very short. Kaddafi pretty much disappeared from the world scene after the bombing, and hasn't so much as uttered a word of defiance toward the U.S. since.

This doesn't preclude the possibility that the SEAL's were used for covert recon or other operations in Libya that still remains classified. Acknowledgement of SEAL activities by the U.S. is generally confined to wider conflicts like Iraqi Freedom, Vietnam, etc., rather than limited military involvement.
