Hour # 109 of playtime it finally dropped - 15th wave reward for Kiliken defense mission in Venus.

Just afterwards I got my first Focus mod in separate run of same mission.

Just a theory, but during those specific two Defense missions, our team was killing waves extraordinarily quickly. Fastest I've been a part of. Seems possible that the rare mod drop rates are affected by how fast you complete the objective. For defense missions that is.
