Another female badass movie and I am lovin' it!

This is a must-to-watch TV series.
What is different? both leads are strong, stone-faced warriors who are willing to sacrifice for the country and the team ???
War always involve human lives and this drama series considered it as no-exemption - no matter how important a character in the drama is, all lives are dispensable.
On the drama flow: I loved how the main characters interact with each other and the minor characters.
