  An outstanding goal of physics is to find solutions that describe hadrons in
the theory of strong interactions, Quantum Chromodynamics (QCD). For this goal,
the light-front Hamiltonian formulation of QCD (LFQCD) is a complementary
approach to the well-established lattice gauge method. LFQCD offers access to
the hadrons' nonperturbative quark and gluon amplitudes, which are directly
testable in experiments at existing and future facilities. We present an
overview of the promises and challenges of LFQCD in the context of unsolved
issues in QCD that require broadened and accelerated investigation. We identify
specific goals of this approach and address its quantifiable uncertainties.
