From Avalon Hill FAQ
Wehrmacht Expert Sniper says,
â€œCrack Shot â€” This unit gets +1 on each attack die.
Superior Camouflage â€” While this unit has cover, enemy units canâ€t attack this unit at medium or long range.
Headshot â€” Once per game, instead of attacking a Vehicle, you may roll six attack dice. If you roll three or more successes, put a face-up Disrupted counter on that Vehicle. This counter isnâ€t removed at the beginning of the next casualty phase.â€
Q: Does the Crack Shot ability apply to Headshot?
A: Yes. The Crack Shot ability modifies attack dice, so the Wehrmacht Expert Sniper rolls successes on a 3 or higher.
Q: Does â€œhave coverâ€ mean that the Sniper has to succeed at a cover roll to get the Superior Camouflage ability?
A: No. A unit â€œhas coverâ€ just by being in hex filled with defensive terrain. This means that a Sniper with Superior Camouflage canâ€t be attacked directly at medium or long range while itâ€s in a forest, hill, marsh, or town hex.
