No “need” for adjustment, but those things ‘launch platforms’ look like dismantled school yard equipment.
Call it a Palestinian School Yard swing set. That is their “playground”. I joke but it might actually be the case, the Palestinians put launchers in just such places, daring retaliation.
That's exactly what they are. These rockets are welded up out of 4" water pipe. All home-made. Light it and run for your life, because if the IDF doesn't spot you, your own munition just might. These are the ones they used in Gaza to harass Sderot until 'Cast Lead' put the kibosh on that.
