Seriously, there is no reason that they shouldn't have them. US have absolutely no proper counters to an enemy sniper. The utility car is instantly destroyed (and snared) by panzerfausts and even then the AT gun destroys any light vehicle in 2 hits (regardless of armor skirts).

First of all, Pathfinders.
Second, the fact that M20 has counters doesn't mean USF doesn't have effective anti-sniper counters. It looks like the real problems aren't snipers, but inability to dodge anti-tank threats. Seeing as AT is far more prevalent than snipers, you're worrying about the wrong thing and fantasizing snipers as being the solution.

US have nothing but infantry units that they HAVE to make and these units are easily countered with MG squads.... you spent all your resources trying to kill a sniper.

Then maybe you should have engaged everything else? Ostheer has smaller squad sizes.

I don't understand why US never had snipers ported from COH1, there was a reason the US faction had a weapons support center, and that was to deal with MG's, mortars, and other snipers. Why would you leave MG's, mortars and snipers for OST, but then take them away from US? Diversify this game and give US proper units to counter so it comes down to gameplay and not blind luck.

I'd take the reason being that they were designed to fight against different factions in that game. That's like saying I don't understand why you don't speak French, since I do and so does everyone else in Quebec, so why not some guy from New York? How would cloning a unit to suit a particular person's gameplay style add to diversity as opposed to less diversity?

I don't see how USF having problems with snipers equate to a need to have sniper units themselves. Would USF snipers actually solve the problem you're having?

Lastly, if USF suffers so much from snipers, then why are they arguably the best faction to play in PvP?

End of the day, it sounds like just another L2P.

Several elements of CoH1's experience system was cool, but many more were not. Unsurprisingly this gave veteran players a bad taste so it's no wonder they're all over OP for it.

It sounds like OP just wants a similar diversification of veterancy among COH2 factions, it is only natural to look at past titles for inspiration. By now he's got the gist that we all hated it and don't want a clone copy...whether that's actually what he wanted is not clear, since the topic is assymetrical systems with a reference to the first game, not "make it like CoH1".

If you really want CoH2 to have a more diverse system, I say make the effects different.
For example, from the start the vast majority of CoH2 units simply unlocked an ability in vet1. Since then patches have removed some units' vet1 abilities since they sucked. Fewer units, especially OKW, unlocked more abilities in places like vet4.

There's a huge lack of consistency that used to exist, so it's that much harder to make design a system where one faction has a particular veterancy flavour. If, for example, Soviet units started at 5-men but all of their vet2 unlocked ability for a 6th, that would be cool. But then you have things like that would work in 1v1, but unlikely in 4v4, especially considering squadwipes.

If you want to "buy" XP, then the system should only be something like increasing XP rate. This would work for UKF since their unit design is largely small and expensive but tough; losing a vet3 Tommy would be pretty bad, but not as bad if you bought an upgrade that lets them vet a bit faster so new squads have an easier time catching up to Jerry and his vet5 Panzers.

USF's officer squads gain XP from nearby friendlies as well as themselves, though in exchange they weren't blob-centered support units like Axis officer squads. I liked Rear Echelon's 5th man unlock at vet2, I kind of want it to be applied to more USF squads, if not all.

On way to reduce blobbing is global effects, for example the OKW Sturm Offizier wouldn't boost units in proximity, but boost units in the entire map's friendly sectors. Under this effect you need not keep him close to your Volks because they already have the effects.

I'm also thinking of a "Kill Assist" modifier to XP, whereas a unit that indirectly contributes to damaging an enemy target gains some XP, this allows some units with lesser firepower and a greater utility role to gain XP without having to fight. Naturally weaker units would rely on this more than combat units for the majority of their XP gain. I don't know if the game can ever handle such individuation of information, though.

But aren't they like absolute shite in performance?

I personally think SU-85's self spot should just become a vet1 unlock. At least then you got to either use T-70 or other units to scout, and once you vet up you don't need them anymore. In most cases I often use other units to scout because of the narrow sight cone, anyways.
Or just reduce the increased sight range max so it's not technically self-spot.

Maybe it can get an upgrade to repair nearby vehicles when out of combat, like the M3 halftrack from Ardennes Assault? It can be unlocked after building T3, and removes transport and/ or machine guns as a drawback.
It'd still be a light vehicle but can actually be of use when tanks are out. And like other repair abilities only vehicles not in combat get repaired when nearby. Very useful when no engineers are around, yet not so durable that a smart enemy would just try to headshot it worth some panzergrenadiers or a tank rush. By the time you've got tanks you'd want something to help them out besides engineers, which may be doing other things like taking points.

Only real problem is that Soviets have the most doctrinal choices for repairing vehicles.

As for ambulance being historical, that's nice but irrelevant due to the fact that HQ has medics, and it would encourage USF style blobbing.

Late-game camo unlock wouldn't be bad either, especially in that stage you'll have lots of AT that would easily wipe it out, and the camo could toggle off mobility and shooting, it would then be what it's named for: a scout car. I'd still take a T-70 over that, however, at least the latter has better armour, gun, speed and overall utility.
