Aspects of the dynamics of walking technicolor models are expected to have important consequences for technihadron production at hadron colliders. Hard-mass enhancements characteristic of walking technicolor raise technipion ({pi}{sub {ital T}}) masses relative to technirho ({rho}{sub {ital T}}) masses so that the decays {rho}{sub {ital T}}{r arrow}{pi}{sub {ital T}}{pi}{sub {ital T}} are either suppressed or forbidden altogether. Thus, {rho}{sub {ital T}} can be unusually narrow with unconventional decay modes. Large weak isospin breaking in {ital U}- and {ital D}-technifermion masses (required for {ital t}-{ital b} splitting) leads to neutral {rho}{sub {ital T}} and {pi}{sub {ital T}} that are ideally mixed. Finally, multiscale models of walking technicolor in which the light-scale technifermions carry ordinary SU(3) color can have color-octet {rho}{sub {ital T}}'s which are produced strongly in parton-parton collisions and are within reach of the Fermilab Tevatron. These would appear as narrow, well-separated {rho}{sub {ital {bar D}}{ital D}} and {rho}{sub {ital {bar U}}{ital U}} resonances in dijet production or in {pi}{sub {ital T}}{pi}{sub {ital T}} production with a limited number of final states.
