Spotting with infantry

[CDavidc]

Hi guys, I need a little advice regarding spotting with infantry. So my guys are in prone position in a rather open field, with some low vegetation around them providing concealment. Understandably they don't really want to go to kneeling position possibly revealing themself, but I really need to take my chances, because I know there is a tank in front of them, and I need positive ID. How could I make them go kneeling while spotting? I tried giving them the Target armor arc command, switching between hiding and not hiding, but nothing seems to work for several turns now. (They are also well rested...)
