I'm in the process of creating a log leaders book. Does anyone have any templates or quick reference sheets they can share?

Have you looked at the CASCOM one stop page?

To begin with start with:

1) Platoon/section Roster with individual stats (PR, BRM, MEDPROS, etc...).
2) Section’s maintenance status.... and who’s assigned to each piece of equipment.
3) Unit training schedule
4) Unit METL and it’s current assessment. Although the lowest level for METLE is at the Company leve I would simulate it and adjust it to the platoon/section as well.
4) quick reference to the most used publications... ARs, FMs, TC, etc...

I would keep alll of the aforementioned in a binder but will keep an updated electronic version as well. MS OneNote is a good tool as well as Wunderlist.

This is off tangent but did you get a chance to look at the German's logistics in WW2?
