The three anti-aircraft companies were deployed in Sicily to guard rail installations: the 203rd in Palermo, the 204th in Syracuse, and the 205th in Agrigento. All three companies were destroyed during the Allied invasion of Sicily. The II Replacements Battalion remained in Yugoslavia when the 21st Infantry Division "Granatieri di Sardegna" returned to Rome. The battalion was disbanded by German forces after the announcement of the Armistice of Cassibile.
