1. A firearm training system for selectively generating images onto external target elements, comprising:
one or more specified target elements each having impact surfaces at least partially coated with a photochromic or thermochromic substance;
one or more portable devices selectively mounted with respect to selected ones of the external target elements, each comprising:
a housing accommodating and configured for optical projection of non-visible light from one or more laser sources and one or more diffractive optical elements,
one or more audio outputs, and
a device controller configured to direct a projection of light from one or more of the one or more laser sources, and further to direct audible signals from the one or more audio outputs, according to a programmed target stimulus arrangement,
wherein the at least partially coated impact surfaces of the one or more specified target elements are configured to undergo one or more of a photochromic reaction and a thermochromic reaction with the projected light to display the programmed target stimulus.
