I would like to make a proposal concerning the "SAW":
The M249 is designed to fire shells from both magazines and belts. Therefore the M249 provides two firing modes: 1000 RPM (high in INF) and 750 RPM (low). These firing modes exist because a magazine contains a feather which pushes the next shell into the chamber, while the belt has to be pulled in by the M249. The additional time and energy which is needed for this pull forces the M249 to be fired with "only" 750 RPM when belt-fed.
Infiltraiton 2.9 features both firing modes for both magazines and belts. Though this isn't wrong, it could be improved:
I'd suggest that the M249 jams after a few shots when it's fired belt-fed in high firing mode. In this case "Jam" would mean that the gun is unable to complete the reload-process ending with an empty chamber and a relaxed feather. You would then have to pull the...... (loading device on the right side of the gun, insert the proper word here in order to transfer the next bullet into the chamber. If you don't switch down to low firing mode before deploying the weapon again, it should jam again after a few shots.
So in the end, the M249 loaded with magazines could be deployed in firing mode "high" and "low", while the belt-fed M249 could only be deployed in firing mode "low", as it is in the real world.
(If i'm mistaken in any details, feel free to correct me)
