In FOG (I only play digital, presumably this is the case in the tabletop version as well), not only are Spanish Caetrati classed as light infantry (fine by me), but also as ranged skirmishers (or whatever that's called).
But was not FOG developed by the guys at Osprey? And this is what one Osprey title has to say about the Caetrati:
So unless this source is in error (and I guess that some might say that it's out of date, going back to 1982, after all), the Caetrati in the game shouldn't function as ranged skirmishers, but maybe more like those units (mostly cavalry?) that can disengage with medium and heavy foot after plowing into them and chopping them up some. It always chafes me in game when my Caetrati face even odds against other javelineers in a straight fight. Caetrati should own other light infantry! No? I could be completely off base here."The caetra was used in conjunction with the falcata sword and the Spanish light infantry were famous for their ability, speed and agility in this type of sword-and-buckler fighting. ... The Iberian swordsman with falcata and caetra should not be excluded from the heavy infantry, for, despite his lack of defensive equipment, his style of sword-fighting verged on the acrobatic, and his caetra and falcata made him more than the equal of any Roman legionary in a straight sword fight."
