NGP'85 Patrolling feature....huh?

[Kuriltai]

And yes, it only works against Partisans (although logically it should be applicable against any units in Deception mode as well. Yet it isn´t).

I was under the impression patrolling was effective against SF as well.In a recent D85 game I actively patrolled roads where I knew there was a deception unit in order to negate their effects.I thought it was working.
Was it just wishful thinking ?
