  The results from a search for chargino-neutralino or chargino pair production
via electroweak interactions are summarized. The results are based on a sample
of $\sqrt{s}=13~\mathrm{TeV}$ proton-proton collisions from the LHC, recorded
with the CMS detector~\cite{cms} and corresponding to an integrated luminosity
of $137~\mathrm{fb}^{-1}$. The search considers final states with large missing
transverse momentum and pairs of hadronically decaying bosons WW, WZ, and WH,
which are identified using novel algorithms. No significant excess of events is
observed relative to the expectation from the standard model. Limits at the
$95\%$ confidence level are placed on the cross-section for production of
mass-degenerate wino-like superpartners of SU(2) gauge bosons,
$\widetilde{\chi}_{1}^{\pm}$/$\widetilde{\chi}_{2}^{0}$. In the limit of
nearly-massless neutralinos $\widetilde{\chi}_{1}^{0}$,
$\widetilde{\chi}_{1}^{\pm}$ and $\widetilde{\chi}_{2}^{0}$ with masses up to
870 and $960~\mathrm{GeV}$ are excluded for
$\widetilde{\chi}_{2}^{0}\to\mathrm{Z}\widetilde{\chi}_{1}^{0}$ and
$\widetilde{\chi}_{2}^{0}\to\mathrm{H}\widetilde{\chi}_{1}^{0}$, respectively.
Interpretations for other models are also presented.
