Rebel Roman general Quintus Sertorius is one of my ancient world favorites. He waged a brilliant six year guerrilla war against Rome, at times driving them out of Hispania. Badly outnumbered, he inflicted stinging defeats on the Romans and nearly captured Pompey. After reading Philip Matyszak's superb Sertorius and the Struggle for Spain, I was primed to paint the Spanish again. Without further ado, here's Sertorius' Lusitanians, version 2.
Lusitanian Scutarii: In L'art de la Guerra, the Sertorius option allows scutarii to be upgraded from impetuous swordsmen (not too good) to impact swordsmen (better!). That reflects Sertorius turning the Lusitanians into a well-drilled army. In game, the scutarii are better in terrain and fight even at impact with legionaries. They don't have equal staying power in melee as medium foot have less cohesion to lose than heavy foot. And of course, legionaries armor helps in melee as well.
If you'd like a quick read on Sertorius, take a look at an old post I wrote here. If you want a deep dive, I highly recommend Philip Matyszak's Sertorius and the Struggle for Spain.
