After a little reading and photo scanning on the Facebook page it appears to be a simplified and playable version of variable length bound.
The "round" is a segmented wheel or time clock where a marker for each unit is placed depending on when it last activated and what action it then took.

When the turn advances to a segment, unit markers (chits) in that segment indicate which units may activate. When all units in that segment have activated, game play advances clockwise to the next segment and units in that segment are in turn activated.
Activations take a specific amount of "time" (segments) depending on the action. For example moving a unit might advance the chit two segments and placing a unit on over-watch might advance one.
It looks like an interesting system and I will be purchasing it.
Disclaimer! Not only have I not played the game, I haven't even read it. Hence, all of the above is pure conjecture.
wonders why create different 3D models, if you can create one that can be customized?
