I need help translating, "To suffer, so that others may not." into Latin.

The idea behind this phrase is, as a soldier, I jeopardize my health,
safety, etc so that other people may not have to know this aspect of
life.

I've looked at web based translation tools and they all come up with
multiple dialogs. I'd prefer to consult a person, someone that is
familiar with Latin and get a more educated opinion.

The dialogs you got from the translator tools are probably not very
good. That's because "to suffer, so that others may not" is a sentence
fragment (the translators work best on whole sentences, especially
with Latin) and because "may not" is ambiguous in English.
It's been a while since I studied Latin, but my suggestion is "Pati,
ne alii patiantur." It's simple Latin, it says, literally, "to suffer,
lest others suffer;" it uses the simplest grammar that gets the point
across.

Other suggestions involve changing the English:
"patiuntur alii, ne alii patiantur:" "some suffer, lest others
suffer." I like this one- I think it sounds the msot Latin. It has a
balance to the sentence that the Roman poets would have appreciated,
since it uses a device (chiasmus, or ABBA word repetition) that was
popular in literary Latin and Greek.
"Passi sunt, ut alii habeant pacem:" "they suffered, that others might have peace"

If you print one of these, I recommend either all caps or no caps.

Best of luck.
