Had this been a platoon of women recruits, it is unlikely that the dynamics would have been the same. Because women have been raised to follow the rules and not be conspicuous, stepping out of the formation and speaking up to encourage another soldier would have been contrary to the norm. The women would have been more concerned with their individual performances during the test and remaining in formation as required. Of course, military training changes many of these traditional attitudes, but this example illustrates a basic difference between men and women when it comes to teamwork. With men, every team has a mission and everyone has a role.
Someone is in charge, and there are subordinate leaders as well as workers, or followers.
The roles may change with the task, but basically the team works together to get the job done, whatever it may be. Everyone is important to the team, and everyone is expected to contribute. When the team succeeds, the whole team celebrates. When the team fails or is struggling, the team members pick up one another and keep going. Women are not as accustomed to being team players and are often more comfortable working independently.
