I was quoting from my own experience in Basic Training (1969) plus some assorted reading. What I was illustrating was the in-group jargon/taboos of the US Army, and apparently such taboos do not make the official glossaries. I am told that combat soldiers have their own slang and jargon (are you surprised?), e.g. "put your juke-box on rock-n-roll" means to fire your M-16 on full automatic.
"Caliber" as used in your quotes means not the diameter of the barrel but the ratio of the length of the barrel to its diameter.
Your definition 2. of a howitzer has jargon I have never before met.
