10. The standard metric for weighing the value of quantitative advantages of
aimed-re weapons is Lanchester’s Square Law, which states that the military
advantage of increased numbers increases with the square of the combat
ratio. So, for example, a two-fold superiority in numbers actually translates
to a four-fold military advantage. This is because aimed-re weapons can
focus their attacks, bringing all repower to bear at the same time. This is in
contrast with the linear-scaling advantage in additional numbers in an era
of hand-to-hand combat, where phalanxes of ghters could only engage one
person at a time. Under Lanchester’s Square Law, German tanks would have
had to have been nine times better than Allied tanks to compensate for their
three-fold numerical disadvantage.

13. The United States suered 148 battle deaths during the war with 210
coalition partners killed. See Patrick Cooper, “Coalition deaths fewer than
in 1991,” CNN.com, June 25, 2003, http://www.cnn.com/2003/WORLD/
meast/04/17/sprj.irq.casualties/. Estimates of Iraqi military casualties vary
wildly, from roughly 1,000 to over 100,000. For a brief overview of the range
of estimates and associated debate, see Jack Kelly, “Estimates of deaths in rst
war still in dispute,” Post-Gazette, February 16, 2003, http://old.post-gazette.
com/nation/20030216casualty0216p5.asp. For the purposes of calculating
casualty ratios, we estimate 12,000 Iraqi military killed based on the Gulf War
Air Power Survey, yielding a ratio of approximately 33:1. Thomas A. Keaney
and Eliot A. Cohen, “Gulf War Air Power Survey Summary Report,” Washington,

of controversy, not necessarily for the numerical analysis outlined here but
because of derogatory statements in the brief about the performance of the
F-35 Joint Strike Fighter. Adding additional color, the study became associated
with the phrase that U.S. forces were “clubbed like baby seals.” Eventually,
RAND had to issue a clarication. Graham Warwick, “UPDATED: F-35 Criticisms
– RAND claries,” Aviation Week, September 25, 2008.
17. This scenario obviously includes a number of assumptions, some of which
are questionable and some of which are clearly unrealistic, but used to
simplify the analysis. It assumes that Chinese ghters do not turn and run,
even after suering heavy losses. It ignores any possible dogghting kills by
F-22s using guns against Chinese ghters (the F-22 has superior stealth and
maneuverability). And it assumes that U.S. tankers and surveillance aircraft
do not begin to ee immediately when Chinese ghters are seen. The analysis
also assumes, however, that U.S. missiles have a probability of kill (Pk) of 1.0
and Chinese missiles have a Pk of 0. More reasonable Pk assumptions would
tilt the simulated ght further in China’s favor.
