The only thing more accurate than incoming enemy fire is friendly fire. The diversion on the tape you are ignoring is the main attack. Try to look unimportant, the enemy may be low on paintballs. If you take more than your fair share of objectives, you will have more than your fair share of objectives to take. Never draw fire, it irritates everyone around you.
Teamwork is essential - it gives the other team multiple targets.
Always carry a squeege onto the field, cause you'll need it. When your whole body is exposed, count on a crotch shot. If your teammate says I'll circle around, count him out.
