The forced induction of a person into the armed forces. In the USA, this typically applies only to healthy young heterosexual males with low lottery numbers, non-exempt religions & poor political connections. Proponents of the draft cite advantages over a voluntary army: lower cost, ethnic diversity (but not gender), greater governmental reluctance to enter wars. These claims have yet to be documented however. Both Republicans & Democrats are split on this issue & will generally let public opinion guide them. Libertarians oppose the draft as mere time-share slavery, & lacking any of the claimed benefits.
The military draft appears to violate the US Constitution's prohibition against involuntary servitude.
