Rules state that a unit may surrender if out of supply and surrounded by enemy ZOC. The unit must roll against its TER to determine surrender. Does the -2 to TER apply to this roll since the unit is out of supply?
Per the errata (see the Files section), the answer is no:
"9. Galicia Clarification: Use the printed TER of units for the Out of Supply surrender rolls (without the usual -2 TER OoS modifier)."
