For KD time, is it filling a SL position or being hard striped in that position? Also, what will it be like for my family at Fort Jackson?

1. When it comes to KD time is it filling a SL position or being hard striped in that position. I've spoken to leadership, HRC and peers and everyone gives different answers. I ask because I am coming up on the end of my second year in a E-6 position but have only been hard striped for 7 months.

2. My drill orders say FT Jackson SC, now forgive me for being ignorant I have only been stationed at JBLM and Ft Carson and grew up in CA. My only experience with that region is FT Benning and Ft Knox. I only ask because I have 4 young children and we are a black family we will be living on post but should I be nervous, again forgive me for my ignorance I'm not saying all people from there are intolerant but it's just new territory for me?

Thanks
