	Explosions differ from weapons in a couple of important ways.		Explosions differ from weapons in a couple of important ways.

	#First, of course, they are area effect. (Duh.)		#First, of course, they are area-of-effect. (Duh.)
	#Second, they impart [[Damage]] within a narrower ~~range~~ than weapons. Weapons impart from 0 to 2 times their rated strength. (In other words, the [[UFOpaedia]] is showing you their ''average'' strength.) Explosives also impart the average listed damage from the UFOpaedia, but they have a minimum of average/2 ~~(seen in UFOpaedia)~~ and a maximum of 3/2*average. So a blaster (HE 200) does from 100 to 300 damage at ground zero (GZ). You will still receive the damage listed in the UFOpaedia at GZ, on average. But you are guaranteed to get some damage if caught within its blast radius, unlike a firearm, which will hit you (if it hits!) for 0 to 2x damage, regardless of range. Of course, if your armor is high enough relative to the damage roll, it always blocks any actual damage.		#Second, they impart [[Damage]] within a narrower interval than weapons. Weapons impart from 0 to 2 times their rated strength. (In other words, the [[UFOpaedia]] is showing you their ''average'' strength.) Explosives also impart the average listed damage from the UFOpaedia, but they have a minimum of average/2 and a maximum of 3/2*average.

Of course, if your armor is high enough relative to the damage roll, it always blocks any actual damage.

	Average explosive damage to units decreases by 10 per tile away from GZ. At the same time, the maximum damage is decreasing by 15 (3/2*10) and the minimum damage by 5 (10/2). Thus at GZ of a grenade blast (HE 50), units receive 25-75 damage, and at its outer edge (radius=5 ~~inc.~~ GZ), units receive 5-15 damage.		Average explosive damage to units decreases by 10 per tile away from GZ. At the same time, the maximum damage is decreasing by 15 (3/2*10) and the minimum damage by 5 (10/2). Thus at GZ of a grenade blast (HE 50), units receive 25-75 damage, and at its outer edge (radius=5 tiles from GZ), units receive 5-15 damage.

	Unlike for units, explosive damage to non-units (ground, walls, and objects) is constant. Thus a specific explosive will always form the exact same blast pattern on the same type of terrain. It is calculated based on the minimum damage (i.e., average/2) for a given square. Thus it starts (at GZ) as half average damage and decreases by 5 per tile outward. If this value is greater than tile armor strength, the tile will be destroyed. However, a given type of explosive always has the same blast radius, regardless of terrain effects (except if there is blockage by e.g. walls). A Blaster can still kill you when 11 tiles away, even if you're on hard UFO floors which will only be damaged four tiles from GZ.

	To demonstrate a standard example, say a [[Blaster Bomb]] hits a door with 100 HE Block. Any alien unlucky enough to be on the outside would be killed instantly, however anyone on the far (inner) side of the door would escape all damage. This is because the door is a "true" (north) wall and stops the blast from moving inward (even if it is itself destroyed).

This is because the door is a "true" (north) wall and stops the blast from moving inward (even if it is itself destroyed).

	On the other hand, what if such a shot were directed at a tree (14 HE block)? Well, so long as the missile hits it DIRECTLY, the tree (which is an "object", not a "wall") won't block the explosion at all - It'll only provide cover if the blast is side on.		On the other hand, what if such a shot were directed at a tree (14 HE block)? Well, so long as the missile hits it DIRECTLY, the tree (which is an "object", not a "wall") won't block the explosion at all - It'll only provide cover if the blast is side on (i.e., not centered on it).

	Ordinarily the distinctions don't matter much. But there's at least one place where they might - As pointed out by Danial, some outer UFO "walls" hit by Blasters have damage penetration past the wall, even though they "shouldn't" (see first image). What's happening is that some outer walls are actually "objects", same as the aforementioned tree - when they are hit directly, the explosion propagates outwardly from the object as if it did not exist (though the walls to the sides do prevent the blast from spreading in anything other ~~then~~ a straight line). This is very different from a "true" wall, which shows proper directionality.		Ordinarily the distinctions don't matter much.

	See the second battleship graphic, which shows the only true north and west '''outer''' walls on the third floor of a battleship. All other '''outer''' "walls" are subject to blast through, as seen in the first picture. That said, however, HE Block has not been well tested/understood in regard to diagonals.
