Does not change the fact that the Iraqi insurgents still engage in such "tactical" behaviour openly, and with some regularlity, whilst the Western troops there are typically loathe to do so themselves.
How much of this is due to a cultural reliance on "pride" vs lack of training + watching too many Hollywood films which portray this as effective? For example, does the Egyptian Army do this? The Iranians? How about Hizbullah in 2006 or Fatah al-Islam in Nahr el-Bahred?

The point with the last example is that the senior US commander actually judged that it was tactically and operationally inapplicable, however erroneously that judgement was made; in the case of the Arab general, he knew that the mineclearing equipment was tactically necessary and chose to reject it anyway because it would have demonstrated Arab reliance upon Western military expertise; the two examples are not comparable.
Bradley disregarded Corlett's advice because he believed he had nothing to learn from someone who had only fought the Japanese, despite the fact that Corlett had commanded two major amphibious assaults in the face of opposition and Bradley none. This in addition to Corlett being specifically detached to provide advice on amphibious landings by GEN George Marshall. You don't think an irrational pride had anything to do with that?
