Of the nearly 90 women who turned up for pre-selection, 37 progressed to the three-day try out. Modelled after special forces selection, the women were challenged with various endurance and team building trials, such as packing up a 200-pound (90kg) tent, dragging it up a mountain with their legs tied together, and then reassembling it. Only three women dropped out – an astonishing rate, considering that the majority of male ranger recruits typically quit in the first days of try-outs.
While there is an ongoing debate about the extent to which nature versus nurture influences things like dominance and aggressiveness, it's not impossible that suddenly-stronger women would experience at least some enhancement of these traditionally male traits. Additionally, self-entitlement, proneness to anger and bargaining confidence in women tend to be linked to physical attractiveness, so strength may simply replace looks as the impetus behind those personality traits.
