Richard,
The way I see it, we have two solutions:
a) Abuse the GPS trace storage of the base OSM database to store the
movements and modify the renderers to read them.
b) Implement movement through the use of multiple ways / relations,
one for each time stamped movement.
I'm tempted to use b) for troops movements and b) for "born digital"
material like AIS / GPS / radar tracks.
Are you planning to encode units as 'fronts' or as point data with
nato-style unit icons?

one of my main interests in historic mapping is plotting out the
movement of
units in military campaigns and battles, and the first effort i plan
to
make in
openhistoricalmap will be based on the 1908 Cope Maps of the Battle of
Antietam.
has anyone given any thought into how represent something like this?
the Cope maps are at roughly half hour to 1 hour intervals over
the course of September 17th, 1862 and are in the public domain,
as they are US Government publications from 1908. they unit
locations, historic buildings and the road network in the area around
Sharpsburg, Maryland and crops and fields of the period as well.
