It does help to have huge concrete barriers surrounding you. Don't suppose you had those in the Po.
I believe you are referring to the Nebelwerfer (of different calibers). Yes, nasty little device. The Germans were a whole lot more competent than any insurgent (or any Arab military power for that matter. I could tell you a whole lot of stories as to why that is, but it is cultural to be sure.) One thing you can say about your war is that it was a lot simpler. Guidance then, "There's the guy in the other uniform! Shoot him!" Today's guidance "The Iraqi people are not our enemy, but our enemy hides among them" and as a corollary "Be polite, be professional, but have a plan to kill everybody you meet."
Damn-you're good, Capt. That's the one, Nebelwoofer!! Right this minute I am recalling what those shells sounded
like. No concrete barriers . we DUG IN at the walls of the canal. I well see your point of todays situation.
