Why does the game treat US forces as less capable?

[Uncle_Joe]

I think the effect he is seeing is that unis with Thermal Sights (regardless of nationality) tend to cost a lot of points. By and large, US formations tend to have a lot of units with Thermal, giving them a pretty high price-tag compared to formations from other nations that lack copious amounts of Thermal.

To compound the issue, novice players rarely get the most out of their Thermal Sights and dont properly use smoke to mask those expensive units and effectively render them immune to return fire.

Combine the two 'issues' and thats why it seems like US forces cost more and are less capable. However if used properly, you can often defeat large numbers of enemy units with minimal risk and quickly even the odds.
