Only Israel comes even close to this
level of military activation of its population, even though many countries have, or had until recently, some form of mandatory military service and subsequent mandatory paramilitary or reserve service, and I am not aware of any
national or insurgent military force in the world with a higher percentage of women serving than North Korea (about 33 % of soldiers in enlisted ranks and 50 % of officers in the Israeli Defense Force, which would be the
runner up to North Korea, are women).
The TRX is used routinely by all four branches of the military, and can be found in the locker rooms of Major League Baseball teams,
National League Baseball teams, UFC fighters, Olympic -
level cyclists, swimmers &
runners, and many more types of athletes!
