  For a torsion unit $u$ of the integral group ring $\mathbb{Z} G$ of a finite
group $G$, and a prime $p$ which does not divide the order of $u$ (but the
order of $G$), a relation between the partial augmentations of $u$ on the
$p$-regular classes of $G$ and Brauer character values is noted, analogous to
the obvious relation between partial augmentations and ordinary character
values. For non-solvable $G$, consequences concerning rational conjugacy of $u$
to a group element are discussed, considering as examples the symmetric group
$S_{5}$ and the groups $\text{\rm PSL}(2,p^{f})$.
