Before capturing a base or a block of post, you send it to the location of the enemy, udone through the sight. He runs there and marks enemies

Boom-boom initially knows how to search corpses - on his own initiative, the main thing. so that not far and the skin is not spoiled during the act of looting. But most of the soldados simply have nothing to take ... so that there is something - you have to kill them with a pistol and immediately after the shot reload the weapon. Let the dog at least find ammunition ...
In general, with the use of words in games, it’s very easy .... Speech in nature is not to go for a search - the dog must pick up corpses.
And Boom-Boom is not interested in resources in principle - it does not bring and does not even show. And the dog will mark the enemies only after the completion of the series of searches.
