Units within 140th Center of SSO

Hi, I just watched the documentary about the 140th Special Purpose Center and their role in the Krynky offensive, and the end of the doc shows the logos of units within the Center. The last one is the Fire Support Group (FSG), and I’m assuming the first 4 are 1st-4th Detachment/Company/whatever, but you guys know way more about this stuff than I do. If this info is too vague to add I understand, but I thought it might be interesting
