jcscot only from a non-army point of view, but I don't think they did showed Molly in a relatively poor light at all, I think they actually depicted her as brave, willing to roll her sleeves up, muck in, be one of the section, be excellent at her trade and "perform" whenever it was asked of her. As Capt Dawes says in Ep 2, she went above and beyond - recognising intel when she got it, risking her own life for one of her section, treating the injured insurgent. She didn't ask for any special treatment for being a female. She had the intelligence and compassion to get involved, see what was required for the mission. So I don't think her portrayal of the role or the writing did females in the military a dis-service, quite the opposite.
But I understand what you (and your H) mean about some of the "questionable" scenes - the "do you love me?" conversation, the complete disregard for orders in approaching Bashira when she had the vest on, going up to her OC and say she didn't know how she could keep her hands off him, running away from the truck in Ep 4 when she'd identified Badrai. But I think that was the drama, the story, the artistic licence that was required to draw in the middle aged women viewers.
I can't believe this time last week I was watching the clock waiting for Ep 5, and this week in its place, the BBC are offering a documentary onn Tutankhamun
