Why do some experts argue that a paid, volunteer fighting force is actually not more expensive than maintaining the fighting forces with draftees?

the current military forces are actually getting paid less than troops of earlier generations.
those who think troops are getting paid more do not understand the principal of inflation.
the short enlistment periods of draftees actually cost the military more in training and turnover.
with more fighting troops from a draft, military engagements would be shorter and cheaper.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
