We revisit the chiral spectra on charged 1- and 5-branes in the 10d non-supersymmetric \mathfraksp(16) string theory (also known as the Sugimoto model), and verify that they consistently cancel the anomaly inflow induced by a Green--Schwarz mechanism in the bulk. By analyzing the \mathfraksp(16) representations arising from quantizing the fermion zero modes on these branes as well as uncharged 4-branes, we find compelling evidence that the global structure of the gauge group is Sp(16)/ℤ2. We further comment on a possible duality to non-supersymmetric heterotic strings, and explore bottom-up anomaly inflow constraints for 10d effective Sp(16)/ℤ2 gauge theories coupled to gravity.
