Thanks for the heads up, Lyn.
However – and it may well be just me – this offer seems to be a typical, smart-*rse, marketing ploy which implies much and provides little more than nothing.
For me, one or two searches DO provide outline details of a serviceman but, I suspect, nothing more than what you would get as a non-member or non-paid-up member when Ancestry is trying to draw you in. That includes a thumbnail of the records you really want to see which, when clicked on, takes you to an American site where either a further subscription is required (Fold3) or you're invited to go to Ancestry War Records. If you do the latter you start to go around the same loop again, all at the same time being required to spend money rather than enjoy free access for a few days, generously provided by Ancestry to mark an event of great significance and to respect those of our loved ones who sacrificed much.
I should be delighted to be proved wrong.
Chris
