(at around 1 min) Sgt Troy is pouring gasoline from a can along a trail to start a fire. He sets the can down at the corner of a small building, then goes into the building. A few seconds later he comes out, goes to the corner of the building, lights a match, and throws it onto the gasoline trail. The gas can is now missing.
Troy lays down a trail of gas and then enters the building telling his men to get ready. He steps outside to ignite the fuel. The amount of gas on the trail is now far more than the amount he was pouring.
Much of the opening scene is the same as an earlier show in the series. If you go to the 1:05 mark of "The One That got Away Raid" and then go to the very first of "The Delilah Raid", you'll see that they are virtually the same.
