The "official" version of events is that Mussolini was shot by Walter Audisio, a communist partisan who used the "nom de guerre" of "Colonel Valerio".  However, since the end of the war, the circumstances of Mussolini's death, and the identity of his killer, have been subjects of continuing confusion, dispute and controversy in Italy.

By 1988, the army was composed of the 6th Guards Tank Division, 28th Tank Division, 50th Guards Motor Rifle Division and the 514th Territorial Training Center.
