the reality of military action is starkly different from the fantasies used to market it to the public; different in goals, methods, experience, and outcome. rayguns will do nothing to change this.
there was a series of SF novels written by Pournelle, that featured a mercenary outfit called Falkenberg's Legion. aside from the suspension of disbelief required for faster-than-light transport technology, the books were realistic in every other way, including the likely experience aboard transport ships. conflicts were messy, confusing and complex; soldiers and civilians were multifaceted characters with personal agendas; and the series was, at times, a very demanding read.
the novels are about imperfect people using the blunt tool of violence to address situations where there is neither nobility nor compassion. the results of this are predictably ambivalent, solving some problems while creating others. the fog of war, and the pervasive uncertainty of dealing with a terrorist, insurgent or guerilla enemy, with hooks into the civilian population, are portrayed in detail and to great effect.
for anyone who thinks that armed conflict is noble, clean, good-versus-evil, or black-and-white, i recommend reading the series as a counterpoint. the Iraqi situation is messy and complex, as real life should be, and historically, there has never been a truly good solution to any problem in the Middle East.
glad to see that there is at least one game that models military action in a more realistic manner, even if only from a statistical perspective.
