How to engage targets from behind a VTAC barricade, brought to you by Viking Tactics. The 9-hole is a great drill for pushing shooters to figure out how to establish stable firing positions when the rifle can't be aimed naturally. As we always take care to note in our training classes, please keep in mind that we do NOT advocate using a 1/2" thick sheet of plywood for cover. The VTAC barricade is designed to simulate a wide variety of surfaces or shooting ports that might be encountered on the battlefield - from cars to buildings to gaps between a wall or fence. By the time you finish this one, you should be confident in your ability to hit a target as long as the barrel is pointing at it and you can get your sights aligned.
