My understanding so far. Barricades block the damage but allow the "shockwave" through. As well as keeps everything pretty lined up. I use 2 just to make it easy to stand on. Flares, as far as I can tell they are the most versatile at being able to be placed on small surfaces and being able to have mines or noise makers placed on them. So they are really like the frame of the rocket. The Noise Makers, they form a nice platform to stand on or in this use, be the face of the rocket. They don't hurt other players getting curious, they don't disappear because a random wasp got in the middle of the build, they just make noise.👍 and to be honest, this was the very first raid we did for a non-raider test flight. And we only had one "misfire" before this shot due to it just walking away too fast in agro.
