You must first know your interface that is used for building the Sg (Sentry Gun). Now go to a position on the map which is hard to reach (such a around a corner), has a good clear view and build a SG. The positioning of the SG is one of the key elements for it to do well. Keep upgrading the SG until at the 3rd level and then get out the shotgun and get ready to use your EMP grenades. Use your timer on your EMP grenades to hit the enemy, once you've hit the enemy throw another grenade or use your shotgun to mow him down. Always keep your sg at 100% Health and 100% ammo. In the end though your sg will have killed so many people (hopefully) that everyone on the other team will be going for it and eventually it will explode from those evil spy grenades. But then you can always build another one.
Dispencers aren't really that useful but there's some things you can do with them. In attack place one outside enemy base for attack squads to refill up on. In defense place down your dispencer next to the enemies flag and when the enemy runs to get the flag detonate it and then if the enemy isn't dead finish him off with your grenades and shotgun.
Plain and simple go up to your teammate and start wacking him with your spanner\wrench to raise up his armor level to 100%.
