On Pathfinders, I don't mind them spawning in ambient buildings, in fact that seems more sensible. That they are poor combat units should be enough of a drawback, even if you don't count on the idea of giving them a decreased neutralize/capture time. Their use should be towards benefitting over units like the drop antenna and increased sight range, as befitting their status as scouts. An upgrade to use sniper weapons as a munitions ability woudln't really change that, since it costs munitions and basically turns them into soviet scout sniper squads that are just as vulnerable to anything but a lone squad. Another way to "nerf" them would be increased dispatch cooldown. If a unit takes forever to re-deploy they are that much more valuable, even if the cost itself is low.
As-is, the airborne pathfinder, and even the recon pathfinders, aren't much different from engineers, you use them to do pretty much anything else that riflemen shouldn't be bothered doing, like capture points and extra meat to an assault. Their potential to do more indirect utility, to me, seems wasted.
I Gotta say it again, i really hate spawning in buildings, this would also increase their cost by quitte alot for a 2 man utility squad. (well if it ever gets to a 2 man squad, but in this game it would only make sens). Once given the german camo and squad reduction, they should be able to move around fairly easely and not need the building deploy at all. I whanted to add the old concealment smokes to desengage since they have no chance in a fight while their use forces them to be pretty far away.
The marskman ability isn't a "sniper" you give them but for a certain amount of MU and a cooldown, you fire a single sniper shot. It was the skill that the brits would get for their rifleman once upgraded with recon kits. It gives them a very sporadic combat utility such as sniping an MG before your paras assault or something like that.
Overall, it really gives the airborn company flexibility and intel to be able to fight out numbered without giving them raw power.
