Smoke screen operations assault landings

Leghorn marked the end of American participation in port screening in the Mediterranean Theater of Operations. Rear area missions gradually petered out with the diminished effectiveness of the Luftwaffe. The lyid and 179th Smoke Generator Companies, by now the only U.S. smoke units in Italy, turned to a type of employment that had evolved earlier in the theater—the use of smoke in forward areas. But before the development of that mission smoke units had been used in assault landings.
