Depends entirely where the sniper intends to use it.
If you’re interested, look up Carlos Hathcock, a USMC sniper during the Vietnam war, and considered one of the best snipers for a very long time. I don’t recall the details offhand but one of his confirmed kills was a high ranking military officer. He spent something like 3 days in a gillie suit crawling something like 1000 yards across a field, took out his target, and successfully evaded troops searching for him that walked within feet of his location.
