Unarmored Fighting Vehicles Unarmored military vehicles,
either specially built for the military or adapted from commercial models and
used in combat-support roles. Although armored vehicles (e. g., tanks) are the
more glamorous war machines and garner most of the publicity, modern armies
rely on tens of thousands of "thin-skinned" unarmored fighting
vehicles (UFVs) for an almost unlimited variety of purposes. These vehicles
include not only motorcycles and cars but also light and heavy trucks, buses,
ambulances, tractors, wreckers, fire trucks, snowplows, amphibious vehicles,
and construction equipment. The backbone of any army's UFVs is the truck (lorry).
Although it might be argued that the first UFV was Joseph
Cugnot's three-wheeled, steam-powered artillery towing device invented in 1769,
the modern use of such vehicles began in 1898 with the use of motorcycles and
autos in the German army's maneuvers. World War I saw extensive mechanization
in the major armies, carried out both by purchase or capture of civilian
vehicles and by development of appropriate vehicles produced by manufacturers,
who were subsidized by government and addressed specifications that emphasized
standardization of controls, interchangeability of parts, and ability to
perform under service conditions. At war's end in 1918, Great Britain had
168,128 such vehicles in use. The United States, entering the war 32 months
after the British, had procured 275,000 vehicles. Both nations were able to
achieve a degree of standardization by taking commercially produced vehicles
and modifying them for military work. No all-wheel-drive truck entered war service,
although several were in the testing stage by November 1918.
In World War II, the Axis powers of Germany, Italy, and
Japan produced 594,859 trucks, and the major Allies, the United States, Great
Britain and the Soviet Union, manufactured 3,060,354. Germany was able to flesh
out its needs somewhat with a huge array of captured vehicles and by utilizing
the production of factories in occupied nations, but in doing so it created
immense maintenance difficulties. Germany's great UFV failure lay in its inability
to standardize. It also wasted considerable sums in producing tracked personnel
carriers that carried a mere 12 troops in theater-seat luxury (but that could
also be used as a prime mover) and a tracked motorcycle that could go
practically anywhere-but that carried only two to three persons. The Soviets
also produced tracked trucks but found, like the Germans, that the considerably
higher expense and complexity of such arrangements nearly negated their
superior overland capabilities. The British motor industry turned out tens of
thousands of UFVs, but the troops in the field seemed to prefer the U. S.
product. (For one thing, it was much easier to change gears in any U. S. UFV.)
The stars of the war, for Allies and enemy alike, were the
American Jeep and the "deuce-and-a-half” truck. The Jeep, developed in
1940 by the Willys corporation and manufactured also by Ford, was a 0.25-ton, 4
x 4 (four-wheel drive) truck and command-reconnaissance vehicle that could
operate with ease up to 60 miles per hour, mount a 40-degree slope, turn in a
30-foot circle, and tilt without tipping at a 50-degree angle. With a machine
gun or recoilless rifle mounted, it was truly a fighting vehicle. Its only real
weakness was its vulnerable standard commercial water-cooled engine; the U. S.
auto industry had no off-the-shelf air-cooled engine available. The
"deuce-and-a-half," a General Motors 6 x 6, 2.5-ton truck also
produced by Studebaker and International Harvester, became the workhorse of the
Allied cause in World War II, so widely used that Russians still call
multi-drive axle trucks studeborky (without knowing why). The Germans were more
than happy to utilize captured 6 x 6s, and the Soviets imported tens of
thousands of them through Lend-Lease. The Chinese Nationalists, the Free
French, the British, the Italian Co-Belligerent forces, and every Allied
military force of any consequence were all allotted thousands of 6 x 6s. And at
the end of the war, the U. S. Army, paradoxically, turned over thousands of its
supposedly worn-out 6 x 6s to the German economy to maintain some sort of
transportation net. They soldiered on for yet another decade over torn-up
roads, with minimum maintenance facilities in conditions almost resembling
wartime. The 6 x 6 (along with newer models of the Jeep) continued to be
produced through several model changes, serving in Korea and Vietnam (an
unmatched record).
The Jeep and the 6 x 6 accurately reflected the American
motor industry, which at the time out-produced the rest of the world combined, turning
out vehicles that were often technologically behind their European counterparts
but were more rugged and cheaper to produce and thus would be better adapted to
the rigors of land warfare. Considering the literally hundreds of uses the 6 x
6 was put to, in World War II and in war and peace in the decades that
followed, it may be arguably the best truck in history, military or commercial.
The contemporary era abounds in thin-skinned military
vehicles, with Third World nations vigorously developing and producing their
own designs so as to strive for military self-sufficiency and underwrite it
with the proceeds of sales abroad. But the U. S. military seemed to have
retained its UFV lead over its last remaining major military rival, the former
Soviet Union. In the Gulf War (1990-1991), those anti-Saddam Hussein coalition
forces unlucky enough to miss out on being issued the U. S. Army new high
mobility multipurpose wheeled vehicle (HMMWV, and now, like the Jeep, produced
for the civilian market), sometimes "hotwired" Iraqi-Soviet UFVs to
gain some battlefield mobility. After about 300 miles of use, these enemy
trucks failed because their transmissions had worn out. There were no reported
significant difficulties with the HMMWVs. Unglamorous workhorses the UFVs may
be, their use in large numbers can be assured in the wars and near-wars of the
foreseeable future.
Interesting to see the Italian copies of the German half-tracked vehicles, and how none of the British and French vehicles featured had dual rear axles, unlike the German vehicles.
