Yeah, I'm still debating actual military mission vice exercise.
Landing exercise makes for a good excuse to have some Army types among the grouping, too. Could be cool, different radios and RTOs, ah, "coordinating," yes, that's it, coordinating.
Exercise means having only a "bad landing" for, say an LCVP; rather than a full broach, which was my first thought. Hmm, might be an excuse to build n LCP(L)--which we were not 'sposed to ground on the beach (but my, didn't the sand strainers get full a time or two . . . )
BTW, always dreaded that some Flag would decide that Aransas, or Crystal Beach, or Surfside would make a nice "public spectacle" of the might & ability of Our Forces. But, that would be a completely different dio <g> Mike boat mired, hard, on a sand bar a mile offshore, with many embarassed hands (hmm, couple dudes in a johnboat fishing in the "shade" would be just about right . . .)
