a question on reach

[big teej]

lets say an ogre (large creature) has a spiked chain, giving him a 15 foot reach.

lets say that he has two buddies flanking him.

can he attack through their squares to hit someone past them?

Yes. His allies would grant the target a +4 bonus to AC. See the part about soft cover. (http://www.d20srd.org/srd/combat/combatModifiers.htm)

Also, a Spiked Chain, as a reach weapon, doubles natural reach. An Ogre has 10' natural reach. Double 10' is 20' reach.



Reach Weapons

Glaives, guisarmes, lances, longspears, ranseurs, spiked chains, and whips are reach weapons. A reach weapon is a melee weapon that allows its wielder to strike at targets that aren’t adjacent to him or her. Most reach weapons double the wielder’s natural reach, meaning that a typical Small or Medium wielder of such a weapon can attack a creature 10 feet away, but not a creature in an adjacent square. A typical Large character wielding a reach weapon of the appropriate size can attack a creature 15 or 20 feet away, but not adjacent creatures or creatures up to 10 feet away.

Note: Small and Medium creatures wielding reach weapons threaten all squares 10 feet (2 squares) away, even diagonally. (This is an exception to the rule that 2 squares of diagonal distance is measured as 15 feet.)
Bolded for emphasis.
