I’d like to hear your advice for combat if so.

Here's an advice for ye: Use the skirmisher and bring a friend using an assault, then flank em' with smoke. Command your friend to rapid shoot & throw grenades at the enemy positions. Don't work¿ A second advice: Use recon and a friend that uses Skirmisher, then command your friend to rapidly throw smoke bombs. Do spots, And aim. I hope that helps

Finally, someone who actually took this post seriously. I enjoy skrimisher flanking ( Dropping smoke on an enemy gathering point, going around and then releasing hell using the meele weapon)

Also, question: Do you think the supports (execpt GERMANY and BRITIAN) are 'real' supports?

More like NCOs to me.
