Scout missing in "Kill the Scout" mission

Hi,

 

I have spent several hours since starting this game, searching for the Scout in the “Kill the Scout mission”, which is apparently near the first base, behind a rock.

 

Well, I’ve searched behind all the rocks. Several times. It isn’t there.

 

Can you please just mark the mission done so I can proceed with the next missions or something?

 

Cheers,
