text: The 1970s Enugu Rangers won a nationally organised tournament in 1970 which allowed them to qualify for the 1971 African Cup of Champions Clubs. Rangers lost in the quarterfinal 0–3 on aggregate to ASEC Mimosas.
  In the same year, they almost achieved domestic success in the Nigerian FA Cup cup as well, but lost the final 2–1 to Shooting Stars F.C.
  After winning the 1974 double, including a 2–0 cup final win over Mighty Jets, the Enugu players were given cars and promotions at the Nigerian Sports Council.
  Rangers lost the 1975 African Cup of Champions Clubs to Guinea's Hafia FC, earning left-back Silvanus Okpala the nickname "Hafia" for his poor play in the final. Enugu had overturned a 3–1 defeat in Egypt in the semifinal to qualify for the final. Founding Ranger Ernest Ufele retired after the defeat.
  In 1977, the club, now managed by their first-ever captain, Godwin Achebe, faced ASF Police of Dakar in the quarterfinals. Held to a goalless draw at home, Rangers took the lead twenty minutes into the second half of the away leg, silencing the Senegal stadium, and eventually winning the match 2–1. After the game ended, team members were physically assaulted by Senegalese fans, according to Nigerian press reports, and three were stabbed. A military plane was flown to Dakar to evacuate the victors.
