[star wars] Why does the rebel fleet at the battle of endor bring transports (the round ships that we have seen to be unarmed troop transports)?

Did they expect to board the Death Star or for a land battle to commence?

According to wookiepedia (Canon) the GR-75 transport has  4 twin laser cannons on it. So it wasn't completely useless in space combat. And it seems like the Rebels went all in for that final battle, makes sense to bring every combat capable ship into battle. 

That or they had rebel soldiers on board and were planning on landing on Endor.
