Does anyone have a good example of a decent battle roster that I may see?

Last, First init. Middle init., Rank, EDIPI, Blood type, equipment SN

If you are looking for a Battle Roster to drive casualty reporting, the S1 takes the manning roster And uses the first two letters of the last name and the last four of the social to issue battle roster numbers.

Not sure if you want the battle roster to do something different. If you are talking about a document that matches assigned personnel to deployed tasks and duties, that's different and is HIGHLY contingent on the MTOE, UMR, assigned METL, and mission analysis with 100% visibility of assigned missions and specified, implied, and essential tasks. NCOs in the RIP process have to be included to capture all the soldier tasks like ECP, Force Pro, etc.

Getting someone else's won't help with your mission analysis, organization, and manning.

Who is it for, what is the purpose, what do you want to track, does it feed into other systems? Is excel the best format for it's ability to sort?
