speed of M8 greyhound, M20 & M3 scout car

[Ironfist]

Unit 28 (M8 greyhound) in OOB12 (US Army) has speed of 20. It seems this is too slow. M8 has a speed of 89~100 kph according to the following site.

It is mentioned in other site that M8 gains the nickname "greyhound" by the British due to its fast speed and thin armor. A speed of 20 (60 kph) should not be impressive.

And M20 should have at least the same speed as M8.
I checked OOB12 in MBT, M8 (unit 55) has a speed of 20 while M20 (unit 56) has a speed of 28.

The speed of M3 scout car (unit 133) is 21 (63 kph) in OOB12. At the same website, it has a speed of 81 kph.

Other sites have different speeds, but all well above 63 kph.

Weapon of M20:
It seems that the .50cal MG in M20 is intended for AA. So maybe it is better to be a 50cal AAMG instead of 50cal TMG. There is no turret in M20, only an AA ring.

Another possible error:
Unit 427 (rifle squad) in OOB12 (US Army) has M1 rifle in BOTH slot 1 & slot 4. I think it means someone in the squad is carrying two rifles in game concept. Maybe a mistake?
