Nice character sheet! I tried it out, the specialization drop down menu doesn't work. I made a character, and generating the character was an exercise in futility. Most terms he suffered injuries.
That got me thinking.
In 1968 during the Vietnam War, there were 543,000 U.S. military personnel in Vietnam. There were about 104,000 casualties, both KIA and WIA. That's about a 19% casualty rate.

Math (this is off the cuff, I could be wrong):
Chance of failing survival roll as per
https://www.gigacalculator.com/calculators/dice-probability-calculator.php. Calculate sum <= target number -1.
Injury chance = Survival fail chance x percent chance of injury on mishap table (it's .3 or .5, 2 results of injury or 3 results on 1D6).
Chance of 20 Year Career Survival = Injury chance ^5
Conclusions:
It's more dangerous to work a corporate job than to be in the Support branch of the Imperial Army.
Being a colonist is just as dangerous as being an Imperial Army Cavalry Trooper
Being a Rogue of any kind is about as dangerous as working a corporate job.
Being a Scout Explorer is as dangerous as being a Ground Assault Imperial Marine.
Being a Drifter Scavenger is as dangerous as being a Ground Assault Imperial Marine.
Being a Drifter Wanderer (pretty much a wandering space loser) is as dangerous as being a Ground Assault Imperial Marine.
The Imperium is rough. No wonder people are willing to go on expeditions to Zhodane and rescue people on Ruie. They're going to die anyway.
