It seems that the difference between the pathfinder and JarmenKell
JarmenKell is a SNIPER, able to act on tank, and the pathfinder is a FLESHY_SNIPER, just able to kill infantry.
in armor ini, for TankArmor
Armor = SNIPER 1%
Armor = FLESHY_SNIPER 0% ; does zero damage to vehicles (not just "a little")
so, FLESHY_SNIPER can't do any damage, so impossible to do a KILL_PILOT. SNIPER has a non-zero value, so it can eventually kill the pilot (if it was zero, no action at all could be done on the tank). it's like stinger sites ("***This is required for snipers to be able to attack and kill stinger soldiers! Must be > 0!")
Hope I'm right
