You are totally and completely missing the point of the definition of "adventure" which was given to you earlier.

Allow me re-write it a bit, to allow for you impaired perception.

When Bad Stuff happens to YOU in REAL LIFE (the person would be the reader of the story or the player of the game), then it's a disaster.

When the EXACT SAME Bad Stuff happens to "someone else far, far away" - especially if it takes place in a fictional setting - it's an adventure.

If I were reading about the service in question as a tale told about persons unknown to me, said service would be an adventure. Hearing it reluctantly told to the adult me by my father - minus the humorous incidents which were all he told me about his war service as a child growing up - it was very much NOT an adventure. It was instead a horror story. 

IT IS NOT AND WAS NOT.

The type of frontline wartime maintenance my father helped conduct was potentially LETHAL, even if he was not being actively shot at.

There was the time someone failed to properly secure the elevation spring on the 40mm AA mount he was working on . . . and just AFTER he stepped off of the firing platform, there was an enormous "WWWHHHRRUUUNG!!!!!!" and THE ENTIRE MOUNT (over a TON of machined steel) flipped end over end into the air, then vanished into the ocean alongside with a mighty splash.

There was also the time that a 5 inch deck mount got a LIVE HIGH-EXPLOSIVE ROUND stuck halfway down it's overheated barrel. The approved SOP was to disassemble the weapon, remove the barrel and then carefully disassemble the round using special long-handled tools, while inside a bombproof shelter. This was IMPOSSIBLE in the circumstances. The destroyer was needed back in action ASAP. So my Dad was detailed to hold a hollow steel pipe around the detonator cap on the end of the round, while a senior PO used a SLEDGEHAMMER to drive the stuck round back down to the breach.  

THERE WAS NO RESCUE.

It was remains recovery and damage repair.

Not even the actual burial details practice with real bloated dead bodies. 

YES THEY DO.

When one joins the NAVY - especially the submarine service of which Tom Rux was a part - one is aware that if the ship sinks (whether from enemy action, bad weather or simple accident) EVERYONE is very likely to DIE.

The various U.S. military services are currently losing more personnel to accidents than to direct enemy action, even though we are involved in two (2) conflicts.

While I am aware that you have never served in the military (so you really are an equine animal for presuming to lecture those who have about the military), haven't you ever watched a recruiting commercial? The military SELLS ITSELF as an adventure.

Not sure what a "cptn 2nd rank" is/was. Do you mean a captain in the reserves? If he was assigned to a shore battery in the continental U.S., then the fact that he died while commanding it means he probably didn't die from enemy action. So it would not have been an adventure, even for someone reading about it who didn't know him. However, if the death had been in combat, then for someone NOT your uncle, his death might have counted as an adventure.

As the definition says, it's only an adventure when it happens to someone else. When it happens to YOU or YOURS, it's a disaster.
