Amazing what constitutes "paracord"
US Military issue paracord is specified by MIL-C-5040H in six types: I, IA, II, IIA, III, IV.[2] Types IA and IIA are composed solely of a sheath without a core. Type III, a type commonly found in use, is nominally rated with a minimum breaking strength of 550 pounds, thus the sobriquet "550 cord".
The US military specification for paracord outlines a number of parameters to which the final product must conform. Although it contains specific denier figures for the sheath strands and inner yarns, there are no overall diameter requirements for the cord itself. Below is a table of selected elements from the specification.
