The problem with that particular ad, @Bob, was that while it delivered a "message" that was barely credible to most people watching it, who would probably have thought "umm... that seems a bit of a stupid thing to do in a war zone", which is hardly making the Army look professional, the "message" it delivered to those it was supposed to appeal to, namely strict Muslims and their gatekeepers, was that "we're pretending to respect your religious beliefs, but we don't really give a sh1t which is why we haven't even bothered to check if what we're portraying is correct or sacrilege".Was the bullshit any different from the Frank campaign which suggested that soldiers had the pick of fit, sexy women when the reality was the only lay most got near was sloppy seconds from the Squadron bike?
All adverts allude; they create an image that conveys a message. They don’t have to be be spot on accurate; they’re not documentaries. They don’t create a contract that has to be fulfilled; all they do is attract interest and that only goes as far as the call to action in the ad.
The message that the patrol prayer ad delivers is that the Army is a place of religious tolerance that welcomes people of all faiths without judgement. So faith is not a reason not to join. Only the terminally dim would conclude that it means that patrols stop for prayer.
Whether it was a success or not can only be easily proven by ad tracking.
Only the terminally dim would be happy with an ad that delivered those messages.
