That's a nice post right there. Other thoughts;

Bring more ammo! You'll be burning through BBs pretty fast even if you're not hosing.

Don't discount the psychological effect. Just showing yourself, or your gun can be enough to cause the enemy to change tactics.

If you're in a built up type environment & suppressing look for some plywood or reveting, or tin etc. to shoot at near your targets. Make that rattle while your team flanks.

Have a way to communicate with your team since you'll be on your own. Radio, whistle blasts etc. They can tell you when to shift fire, and you can call in to them if you see a need to adjust the attack.
