1. A munition comprising:
an explosive; and
a munitions structure substantially enclosing the explosive and being formed from a high-strength reactive alloy, the munitions structure including;
a first surface having one or more grooves, wherein the munitions structure is configured to fragment at least partially along the one or more grooves,
a second surface at least partially forming a cavity in which the explosive is disposed,
a first thickness extending between the first surface and the second surface, the first thickness being external to the one or more grooves, and
a second thickness extending between the first surface and the second surface, the second thickness being internal to the one or more grooves, the second thickness being less than the first thickness.
