It turns out that Euroforce has been around a lot longer, they first appeared in the 1996 as a team of heroes in the Marvel Italia. Marvel Italia continued to exist even after the collapse of Marvel UK, producing some Marvel UK related titles such as Wild Angels featuring Dark Angel, and Wild Thing.
The following information I've copied from Comic Vine, who explain it all so much better than I ever could.
Euroforce is the name of an European Team of superhuman, with two incarnation: the original Euroforce, that was created in 1996 by Marvel Italia, the Italian division of Marvel Comics; and the new Euroforce that appeared for the first time in Avengers World n. 8.
The original Euroforce was created by Xavier Marturet and Paco Diaz and lasted a five issues miniserie. The new Euroforce was created by Nick Spencer and Marco Checchetto.
The original Euroforce rose from the ashes of other two team: Task Force and Eurolab. Both those team were part of the Euromind: the European division of the S.H.I.E.L.D., under the directorship of former UN Blue Beret Francois Borrillon, answering only to Supreme Headquarters Allied Power Europe (S.H.A.P.E.).
Eurolab was a scientific research team, composed by high technical/scientific specialist, while Task Force was a rapid-reponse combat specialist unit, usually employed to defend/recover/aid the Eurolab.
The members of Eurolab were Key, Danger, Deep Sight, Nuage and Picaro.
The members of Task Force were Dragonfly, Argento, Blue Condor, Iceboy and Tiger.
Investigating a U.F.O. crash site in Malaysia, Task Force discovered mutated corpses wearing the insigna of the french multinational Nadir Inc., and was attacked by three Japanese “super-armored cyborg mercenaries” called Lords of War (Sakuragi, Kaneda and Oda). The Lords of War killed Dragonfly and Blue Condor, and captured Iceboy. Tiger and Argento survived to the ambush and escaped thanks to the newly discovered Argento’s powers.
Eurolab also was investigating on some case of mutate apparition, and when S.H.A.P.E. ordered an halt to investigations on mutate’s origins, the scientific team started to suspect corruption among the S.H.A.P.E. higher ranks.
Hoping to show the evidence of a conspiracy and to rescue Iceboy, Tiger and Argento joined the members of Eurolab and fled from their base in Spain, but fake evidence was created by their enemy for accusing them of several murders of Euromind Agents.
Francois Borrillon saw the ruse but was unable to prove the truth. Trusting his friends and soldiers, he directed them, now joined together the Euroforce, to investigate in the Nadir’s Malaysia HQ, discovering that it was an A.I.M. base.
After the find of Iceboy, even if it was too late for save his life from mutating experiment, the Euroforce fight both A.I.M. agents and the Lords of War, but while escaping from the base, an attack of the Lords of War make their airplane explode, apparently killing the whole team.
Instead, Euroforce survived, but Borrillon infom the S.H.A.P.E. (and indirectly, the A.I.M.) that the team had perished, leaving them free to operate as a covered team to find evidence of their innocence and of the corruption of both Euromind and S.H.A.P.E.
In 2014, in the City of Dead under Velletri, Italy, a new team called Euroforce appear, ordered by European Government to investigate on strange mystical energy and saving Avengers members Hawkeye, Spider-Woman and Night Mask from angry spirits.
The members of the new Euroforce are Black Knight, Baby Killer, Sliver, Swordswoman and Tumult
The tie between this group and the original Euroforce must yet be discovered, but the Black Knight declare that they are “the new Euroforce”, confirming that they are somewhat their offspring and that the name “Euroforce” have been rehabilitate.
