It's surprising the amount of people that think that only MGs can suppress. As a rifleman, you have 9 clips of ammo. As a semi auto riflemen, it's 5. As a PPSHer, it's 3. It's more than you need.
Why not shoot off a few rounds? Not every shot you take has to be an aimed one at a specific target. Are there enemies in X bunker? Take a few shots at X bunker. Hear a bunch of gunfire at Y location, but don't see any enemies? Shoot a couple rounds off.
While of course the suppression effect in RO is not the same as in real life, people STILL don't want to die. When a bullet goes near someone, they generally get behind cover for a bit because they don't want the next bullet to hit them. Use those bullets. On offense, it's excellent for keeping the defender's head down while you advance. On defense, it keeps the offense from advancing too quickly.
