Taking out high value targets a long way away - so far only 4 HIMARS vehicles have been provided.
Actually, eight have been delivered, with four more on the way, plus three M270s delivered, with a further three to be delivered from Germany later this year.
That's beside the point, though, because NATO and allied countries have delivered about 300 155mm guns, both towed and self-propelled, which are what would be used to attack fortified positions, if necessary.
