An other example: If (logically, from our point of view) firearms are way more leathal than meele weapons on a normal battlefield conditions, then why the heck do space marines use meele weapons soo offten in every media(DaW intro, BL books...)?
1. Space Marines are usually able to dish out more damage in close combat than most types of close range firearms. So when space marines go in for the kill it is the equivalent of sending in a squad armed with shotguns and pistols. Meaning that in some situations, actually using the bolters would be redundant.
2. Space Marines are not like conventional soldiers, they are a specialized force intended for rapid strikes and deployment. Once they hit dirtside they are to secure their objective as fast as possible. This means that they simply don't have the time to take cover in trenches and exchange volleys of fire with the enemy, becoming pinned, asking for airsupport or artillery support etc. etc. They have to get moving. Which means that they might be able to snap of a few shots at the enemy when they have the chance, but as soon as they realize that the exchanged gunfire isn't helping, they have to move in and slaughter the enemy or at the very least cut their way through the ranks so they can reach their primary objective.
