Editing Improvised explosive device (section)

====Directionally focused charges====
Directionally focused charges (also known as directionally focused fragmentary charges depending on the construction) are very similar to EFPs, with the main difference being that the top plate is usually flat and not concave. It also is not made with machined copper but much cheaper cast or cut metal.<!-- I believe that this should be more general and not be restricted to a specific material. This is for one, a "improvised" device. Regardless it should have a citation. --> When made for fragmentation, the contents of the charge are usually nuts, bolts, ball bearings and other similar shrapnel products and explosive. If it only consists of the flat metal plate, it is known as a platter charge, serving a similar role as an EFP with reduced effect but easier construction.<ref>{{cite magazine|title=Superbomb Mystery: The Herrhaussen Assassination|magazine=WIRED}}</ref>
