Platoon Manager
A roster that only knows today can tell you who is here. It cannot tell you who will be here on the 14th, which is the question every plan actually needs.
Today's status is not a forecast
A status column says PRESENT or LEAVE right now. Ask it about a Thursday next month and it has nothing, so the answer gets assembled by asking four platoon sergeants, who each ask their squad leaders, who each check their own notes.
Everything needed for the real answer already exists. The leave was approved with dates. The school has a report date. Those windows cover the 14th or they do not.
Availability is a date question, not a status question
A soldier is unavailable on a given day when an absence window covers that day. That is the whole rule, and it holds whether the absence is in the future, running now, or already finished, because whether somebody was away on the 14th does not depend on what they are doing today.
Ranges matter more than single days
Real planning is rarely one day. A four-day gunnery needs the people who are free for all four, and the useful output is not just a list of names but how many days each person is out, so you can tell a soldier missing one morning from one who is gone the whole week.
The answer has to include the nearly-available
A binary free-or-not list hides useful options. Somebody with a medical appointment on Tuesday morning is available Tuesday afternoon and all of Wednesday, and for a three-day event that may be fine.
Showing the days each person is out, rather than only excluding them, lets whoever is planning make that call instead of having it made for them by a filter.
Watch for the squad that is never available
Once you can ask the question repeatedly, a pattern shows up that nobody sees from a single day: one squad that is short for every event because its people are cycling through schools. That is a manning conversation, and it only becomes visible when availability is something you can query rather than assemble by hand.
What it changes
The visible win is fifteen minutes not spent on a phone tree. The bigger one is that plans stop being built on optimistic numbers. A commander who can see that only nineteen of thirty-one are free for the range will either move the range or change what it covers, and either decision beats finding out on the day.
