  In eikonal and quenched approximations at least, it is argued that the strong
coupling fermionic QCD amplitudes obtained with the help of the newly
discovered effective locality property, depart from a dependence on the sole
$SU_c(3)$ quadratic Casimir operator, evaluated over the fundamental gauge
group representation. This result, in contradistinction with Perturbation
Theory, but also with a number of non-perturbative approaches such as the MIT
Bag, the Stochastic Vacuum Models, and Lattice simulations, accounts, instead,
for the full algebraic content of the rank-2 $SU_c(3)$-Lie algebra
