Yup that's my squad for sieges! Naval officer + 3 Neptunes. The biggest problem is that they all try and fight for the highest number of kills. It's really REALLY hard to maintain their 20 kill per battle average.
My most decorated Neptune officer has 2448 kills after 127 battles (19.3 kills per battle). She is fuming because before the new Neptunes came on the team, she was averaging 30 kills.
