Who were the members of the National Liberation Front?

It really depends when and where you are referring to in
this question, as the name National Liberation Front is very common in
history.

Usually, in American history, we are referring to
the Vietcong rebels in South Vietnam during the Vietnam War from 1964 - 1973.  They were
also sometimes called the National Liberation Army.

Then
you have an independence group in 1960s Algeria with the same name, and a later
political party in that country.  Also, the Sandinistas in Nicaragua were referred to as
the National Liberation Front, depending on how exactly you translate the Spanish to
English and even an organization for the independence of the Ogaden Somalis carries the
name NLF.
