I have heard several different opinion/answers from Senior NCO/Officers. Like it is only used for the first formation of the day, or it is only used if the subordinates are not organized around the formation leader. I reviewed Army TC 3-21.5, and I am still unsure. Are there any concrete answers?

That command would be used anytime You are not standing in a formation yet any time of day or night but the people needed are present in the area and ready to do so. It doesn't matter if its the first forming, they were on a break anytime they aren't in formation and You want them to form up.
I am guessing this question is related to the commonality that many formations are known of in advance, and that the elements take it upon themselves to “form up” before someone officially taking command of it. It’s a great question that SMSgt Lawrence McCarter hit the nail right on the head. The commands that do depend on the time of day are “Fall Out” and “Dismissed.” Either way you hash it, “Fall In” remains a combined command for the position of attention, meant to form elements at any time. It’s alternate, two-part command, (i.e. Platoon, ATTENTION) can be given anywhere, whether formed or scattered about, and all Soldiers should go to attention. A good example is when the Battalion Commander walks into HQ at the beginning of the day. Only use Fall In as a means to organize a formation. Hope this sheds some reason.
