I'll check out Azure. Thank you.
I added my specific request to the original post.

My battalion has five companies, each company has 30-60 Soldiers assigned.
I would like to create a task that every assigned Soldier is required to complete. As they complete the task they would update their individual status and that, in turn, updates the progress of the company and the battalion.
I would also like to add and remove Soldiers as they move in and out of companies and the battalion.
If this is possible, it would allow real-time progress reporting of taskers and benefit overall command and control.

2LT (Join to see) this is much clearer and thanks for elaborating. The owner(s) of the Teams group have the ability to add/remove users (in your case soldiers). That’s the easy part. This may not exactly solve your issue but, creating a Team for each company that you are an owner of would allow you to keep them all separate based on their company. As for “tasks” assigned it might be possible to create a task in one group and then copy that task to each Teams group. I haven’t tested this but it may resolve your issue.
