Could be Combat, bespoke typeface exclusive for Nike, some kind of stencil version of Stratum 2.
Ready-to-go alternatives: Amiral 205, Vafle Stencil
To-be-"stencil(iz)ed": Industry HFF, Quarca Insigne

Yes, it's definitely Combat. Just wish I could get ahold of it! Thanks very much.

Notes, apparently by the designer of Combat:

Stencil versions were produced in bold and black weights.
This image shows where the cuts are placed in the stencil version of bold oblique.
