I don't think any of these examples of dialogue is more than usual banter between soldiers. I'm a BSG fan but I have to say the laughs are non-existent. It's one of the big problems with the show. The best war movies have moments of (usually gallows) humour that make you laugh out loud but I don't recall any moment like that in any ep of BSG. The scripted exceptions of Madame President having one of her borderline hysteria moments with Adama seem geared to make the viewer slightly uneasy, I always think.
