Answer 2

Recent research suggests that a crucial factor in understanding the out-
comes of military conflicts is the extent to which militaries are mecha-
nized—that is, their relative dependence on tanks and armored vehicles
compared to manpower. Since World War II, militaries have become
increasingly mechanized both among the great powers and in unex-
pected quarters of the developing world. Yet the extent of military
mechanization varies widely across states. Why have some states adopted
highly mechanized force structures, while others have not? This paper
tests several hypotheses about the determinants of military mechaniza-
tion. One perspective suggests that strategic factors—including the force
structures of adversaries and neighbors, recent combat lessons, and
internal insurgency threats—shape a military’s mix of manpower and
vehicles. A second set of hypotheses points instead to domestic institu-
tions such as democracy and civilian control of the military. Still other
theories emphasize economic forces and international norms. To test
these and other hypotheses, we construct a new data set containing
mechanization rates for more than 150 militaries from 1979 to 2001.
Broadly, we find significant support for the strategic perspective and lit-
tle support for domestic institutional explanations. In addition, the
results suggest systematic and predictable differences in the ways states
structure their militaries in response to security pressures.
