Nice, but pricey, and the magazines are fragile. There's a point of view that of a paired team, one guy should carry the most precise long-distance rifle available, while his observer backs him up with a semi, which may also double as a night vision device-equipped rifle, particularly if fitted with a silencer. And some teams are going to a three-man configuration, providing a strong back for an extra patrol radio, or an antimaterial .50/.338/20mm rifle, particularly when a backtrail or river crossing can use a cover position. Similarly, airfield sniper teams working from towers work a little better with a third member on the ground for some extra security.
That PSG-1 is mighty heavy to hump for long distances in the bush....
