Yes, god bless your father and the "Greatest Generation".  I have read a lot of the Second World War.  I served 3 1/2 years in the Army and served overseas.  In one of my books, I read a verse that read: "The 88 converted more men to Christianity then Peter and Paul combined".  It was an amazing weapon.  The round traveled at such a velocity that you would be dead before you heard it.  And asd for theyre accuracy, form the book D-Day by Stephen Ambrose.  A soldier on an LVT(coast guard it think).  He said something along the lines of, "the Germans(this is an 88 he was talking about) put a shell 100 yards to our left, 100 yard to our right, the third shell landed on the Coxswains head."  Amazing!
