I too, recall sitting with my ol' man, watching both Victory At Sea and World At War and appreciating his insights. He served in the Navy, first in a PT boat patrolling off of North Africa, then on two sub-chasers in the Central and South Atlantic. They got one U-boat and one whale (by accident, oops!) Or listening to my grandfather, who saw action on the Western Front in 1918 with the U.S. Army.
I served in the Navy in the early '80s, although the closest thing to action I saw was playing cat-and-mouse with Soviet cruisers in the Sea of Japan who were following us. More of an annoyance than the danger my two paternal ancestors saw.
