Several other things changed as well. Up until the middle of MED Cruise 79 we never had Liberty or Pier passes to leave ship. At liberty call we left by presenting our ID Card we kept on our person unless restricted to the ship best I remember. We did have an incident in Venice Italy during the 79 cruise where some guys from The Hole wrecked a bar and darn near got all liberty canceled for the ship for the rest of the cruise. After that passes were issued even to take trash to the pier and I still have my Liberty Pass LOL. Late 79 IIRC also started the uniform changeover. In Sept 80 my division officer did a separation seabag inspection on me and even though I had the older blues all intact I had to purchase the new Crackerjacks before I got out. I didn't need the dress blues because we were in overhaul my last year and had no formal dress blues uniform inspections.
the Bosuns call seems to have been used more in PACFLT in the 70s.
