I-485 Military Service questions

[aless 0]

I'm confused on a couple of the Eligibility and Inadmissibility questions on the i-485 which I am filling in for my father. He had two years of compulsory military service in Italy, during peacetime, as a driver and in an office. I said yes to 49 - "Have you EVER received any type of military, paramilitary or weapons training", and explained he had military service in the additional pages at the end. But then there are a couple more questions a little further on, clearly among a group of very negative questions regarding admissibility, which look like I would have to say yes to, based on the Italian military service. Are these two, copied below, indeed a YES? And if so, do they get their own explanation in the back, which would be identical to the explanation there for question 49 about his having done military service? He never used a weapon against any person but the Italian army certainly did at some point. And saying yes to questions relating to vigilantes and insurgents certainly seems negative. Here are the two negative sounding questions:

54. Have you EVER been a member of, assisted, or participated in any group, unit, or organization of any kind in which you or other persons used any type of weapon against any person or threatened to do so?"

55. Have you EVER served in, been a member of, assisted, or participated in any military unit, paramilitary unit, police unit, self-defense unit, vigilante unit, rebel group, guerilla group, militia, insurgent organization, or any other armed group?
