  The common statement that any consistent quantum gravity theory contains
dynamical objects with all possible charges suggests that there are still a
number of hitherto-unidentified branes in string theory. Here we give the exact
worldsheet description of near-horizon limits of non-supersymmetric $p$-branes
in ten-dimensional $\mathrm{Spin}(32)/\mathbb{Z}_2$ or $(E_8 \times E_8)
\rtimes \mathbb{Z}_2$ heterotic superstring theories for $p=7,6,4,0$.
