If MyHelpers is a simple class and not a registered component in main/config.php, inside your view:

$myHelpers = new \yii\components\MyHelpers();
$myHelpers->findCommandos($con);

Take care to change namespace, because \yii\components namespace suggests something related to Yii official components.

Calling \backend\controllers\SiteController::findVar() should do what you want.

You may want to create a helper class and put that method in it since it has nothing to do with your controllers logic.
