Thus was born the armored cavalry assault vehicle, or ACAV, a weapon system that was called "the champion VC killer of I Corps" by Colonel R.
An improved version of tire ACAV was fielded by the 11th Armored Cavalry Regiment when it deployed to Vietnam in 1966, and other American mechanized units also had their M113s equipped with armor shields and extra machine guns.
The ACAV concept proved exceedingly effective on the nonlinear battlefield of Southeast Asia, even though the insurgents were well armed with RPG-2 and RPG-7 rocket launchers, as well as a variety of recoilless rifles.
The mortar platoon tracks were equipped with what the troops called "ACAV
kits." These were heavy metal gun-shields that protected the normally exposed gunners of the heavy machine guns.
As an intentional by-product, a network of collaborating centers was established and an international spirit of cooperation and camaraderie evolved, as exemplified by the American Committee on Arthropod-Borne Viruses (ACAV) and its various subcommittees that take responsibility for collating a catalog of the recognized arthropod-borne and rodent-associated viruses (7), evaluating their safety, storing voucher specimens, and determining their antigenic relationships.
We suggest that viruses, not simply their genomes, be registered with ACAV, the specialty group on which the International Committee for Taxonomy of Viruses mainly depends for classification of the arboviruses, hantaviruses, arenaviruses, and filoviruses.
