Hello....
Something that may be useful... or not... is the ability to 'breakdown' units into their subunit components, as in Panzer Campaigns. Just because the 'base' unit for a game is set to a 'size'... platoons or such doesn't mean they operated that way all the time.
Most units would send out subunits for 'outposts', observation, pickets, recon and so on. This established a 'barrier' between the main unit and the areas around it. It supplied early warning, recon, observation and scouting and so on. It also maintained a level of concealment for the 'parent' organization. Since subunits are easier to maneuver and conceal, they could observe what was around them from a remote location without always giving away their presence.
Maybe having a 'deployed' setting as differentiated from a movement deployment or deployment that only occupies the hex the unit is in would be an option for the game. Not all units would have this feature, it would be on a case by case basis.
So, I'd like to see the ability to breakdown units at least 'one-level'. So the platoons should be able to breakdown into at least squads. 'It' should not be limited for 'infantry' class units...for example armored cars would send out single vehicles to recon ahead of the main unit so the whole parent unit wasn't exposed to attack from 'hidden' units.
I realize the potential for increasing the complexity of the game, simply 'handling' all the subunits would increase the time for a turn. But on the other hand 'units' would begin performing operations as they actually did. That would be a good thing for a game that is 'simulating' combat operations.. right?
