COMPROMISE:
How about airborne riflemen is included but they can't buy bars. Greaseguns/thompsons. Make them more of an assault soldier without the suppression ability.
Then they will be very useful but not unstoppable because they can't suppress vet 3 kch instantly like they could with bars.
ummm.... you should use them sometime.... you know.
To find out they don't have SF already like rifle BARs for example.
