Demo charge are not mines

Each unit or abilities should have its own purpose with possibilities for creative uses.

Demo charge purpose must not overlap too much over the mine's one.

As i see it:

Demo charges use : (including boobytraping)

Destroy structures :
-Only one per structure.
-Can only be placed on building, bridge, cover, wreck, defensive position like bunker.
-Must have at least a 4 sec arming period but detonate instantly (manual trigger).
-No need to have friendly in sight to trigger.
-Invisible to all but sweeper unit with the same detection range then mines.
-3 sec removing time/ no removing under fire. process must be started again.


-Can't be place on ground/tree or territory flag.
-Can't be placed if the placing unit under fire, building process is stopped immediately and must be started anew.


Mines:
-Must have at least a 3 sec arming period but will detonate instantly.
-Can't be laid if the placing unit under fire, laying process is stopped immediately and must be started anew.
-Invisible to all but sweeper unit with a short detection range (vanilla coh2).
-3 sec sweeping time/ no sweeping under fire. process must be started again.
-Mines must be swept or they will detonated : A moving blob + a sweeping unit will trigger a mine, meaning
a sweeping unit must go alone in minefield to sweep it.
Can't lay a mine in the blast radius of another mine.No overlap.

Mine blast should only disable/hurt/stun units but never wipe them unless they are already at 50% or lower of their hit points.

Give mines and demos to all factions. With guns, they are the bread and butter of warfare.

Important : Mines or any explosion don't trigger demos but minefield can be partially/totally destroyed by any explosion.
