See the TD platoons (41 and 44) in the USA OOB. The integral scout cars are there precisely for that sort of thing, and providing flank security once in place.
WE provide (-) versions without, for the AI and those players who don't want/need them (since the maps are that accurate that actual ground reconnaissance is not as necessary as in real life).
Route reconnaissance also a major job of recce units in real life - rather than head butting the enemy in combat to find them. Part of route reconnaissance is leaving a scout car at a junction or whatever to direct the following columns down the right road, again not a factor in most wargames since the "player-god" has a perfect map and absolute control of all units movement.
No traffic lights, MPs, or street signs are needed in the SP universe
