The HE Charge is one of the equipment items of the GDF Soldier. It is required to destroy the objectives. It works similarly to the Strogg Plasma Charge. You plant it, then you press the interact button, or equip the arming tool to arm the explosive. Then, after a set amount of time (about 40 seconds, there is a HUD element to give you a general idea of how long on objectives) it will explode. HE Charge can be planted anywhere that you can reach. It's good for destroying emplacements, instead of disabling them. They can be disarmed by the Strogg Constructors, so the team must keep an eye on the charge before it blows up.
