Yes. But what was your question? There are many issues here.
I suggest the 1948 Radiological Defense 4 volume set. See if your library can get all 4 volumes on interlibrary loan (don't accept less, all mine could get was 2 so I had to buy them)! It covers many of these issues.
Trenches were dug by both sides in the war. Trenches were used to protect men from artillery and machine-gun fire. Trenches became death traps if the artillery could accurately locate them. Trenches were also death traps after the introduction of poison gas attacks because the heavier than air poison would sink into the trench. Trenches were sometimes very primitive ditches and sometimes were very elaborate with telephones, kitchen, latrine, field hospital, commissary, bunks, ammunition dumps, etc. Trenches were sometimes haphazard and were sometimes extremely orderly, with a front line, a secondary line, and additional trenches for reserves and artillery. Trenches were sometimes dug by one side and later taken and used by the other side. Attacks from the trenches were called "over the tops" -- the men would climb out of the trench and over a small berm with firing positions into "no man's land". There they were exposed to withering enemy machine gun, rifle and mortar fire. Typically they would fix bayonets before attacking and depending on their weapon could generally fire only one shot (or none) while attacking. Very near the end of the war, the Germans developed an effective attack strategy against trenches. Rather than use rifles with bayonets, they gave their attackers much lighter carbines that could fire many times before reloading. They also gave their men hand grenades and flame throwers in some units. These men could attack in lightning fashion in small units and often worked at night. These attacks were much more survivable (for the attackers) than the massed over the top attack. Other strategies effective against trenches were precision artillery and / or mortars; aircraft with machine guns; zeppelin attacks; and attacks from the far ends of the trenches, often with tanks.
There are several submarine museums such as the U.S.S.Ling In Hackensack, N.J. known also as the Naval Museum. They have a small (Sea Hound) type U-boat with cutaway panels 9craft has a Mercedes-Benz Diesel and recently Exide Batteries- certainly Not original gear!- Everything that went into a submarine is of the maximum as regards quality control and accuracy-including certainly compasses. Submarines do a good deal of (Blind navigation) and the compass is mandatory to be of the highest function. Most US subs use or used Sperry Gyrocompasses which were specially made for the Submarine service, looked like drum-shaped robots with the large master motor-generator.-was run all the time except in possible 9Silent runs) when the whole sub was powered down and the Gyro was cut off ( a very dangerous maneuver as if the sub had to suddenly maneuver (say a hail of depth charges!) navigation would be (By Guess and by gosh- say, we were at 270 Degrees (Due west) when we cut off the gyro, back about l5 minutes, H"mm guess 265 average. not a good thing. they had magnetic compasses for such emergency use but normally navigated on the Gyro-compass or Iron Mike ( so called because of the stainless steel construction, not the boxer. Good luck. I do not know of any Japanese compass makers, you would have better luck with surface ship gear more survivable- but many Jap subs were captured intact while under construction at shipyards_After the Fall of Japan Good Luck- BANZAI! By the way Maru applied to a Japanese ship is dErived form Japanese word for Vessel (includes pots and pans also!) I have a Japanese naval compass in my possession that was made by the "Oki Electric Co. Ltd." the company is still in business but unfortunately the were not able to provide any info on the compass. It is a gimbel mount compass and made of brass measuring 3 1/2 inches in diameter. It is air filled (not liquid) and magnetic instead of gyro, and inside seems to be a coil of wire that I assume was to cancel out interference from shipboard electronics.
Triage and treat for most critical injury. If that involves some radiological exposure to medical personal, they will need minor treatment later. Radiological decontamination procedures on burn or blast victims are likely to be more life threatening than original injury.
All arterial injuries are potentially fatal or survivable depending on the amount of damage and the ability to get rapid medical intervention.
One where people walk away from it.
its not curable but survivable. if you survive it the you will never get it again.
It was estimated in 1980 that 30-40% of fatalities in survivable accidents are related to fire and its effects (FAA-ASF-300-1H).
It is densely populated in areas but survivable to date.

Drag. It reduced the fall rate to a survivable speed.
No, survive is a verb. There is no formal adverb for the adjectives surviving or survivable.
Aircraft accidents are not only exceptionally rare, but also frequently survivable.
Because that is the way our head and eyesight is oriented. It is more efficient and survivable that way.
Monosomy X (Turner syndrome) is the only known survivable monosomy.
