3e SRD:Aid Another
From D&D Wiki
|This material is published under the OGL 1.0a.|
If a character threatens an opponent with whom an ally is engaged in melee combat, the character can attempt to aid the ally as a standard action. The character makes an attack roll against AC 10. If the character succeeds, the character's ally gains either a +2 circumstance bonus to attack that opponent or a +2 circumstance bonus to AC against that opponent (the character's choice).
