Gavin, Former Com- mander of the 82d Airborne Division8 Airborne guns figured to play a promi- nent role during the assault onto the island of Sicily on 10 June 1943 when elements of two artillery battalions were to participate in a night drop. However, unusually high winds coupled with poor navigation by aircraft crews and friendly anti-aircraft fires scattered guns and gunners far from the DZs.9 This disper- sion prevented the airborne artillery The 75-mm howitzer’s relatively small size and weight allowed disassembly into nine from making a battlefield contribution paracrate or parapack loads containing gun components and ammunition.
