Just a break down of A heay and light version of the RPG with various projectiles.
The standard would be a heavy HEAT round, in an advanced version the HEAT round would be a double charge version to defeat spaced aror and reactive armor packets. the round can be encased with preformed fragments to allow it to serve both anti-vehicle and anti personnel roles. It would not be as effective as a Purpose designed Fragmentation warhead but it would be enough to serve in a pinch.
A smaller High Explosive Fragmentation round would be used against groups of infantry or enemy strongpoints. Advance versions of this round would be capable of airbursts or delay detonation allowing it to explode over a target or break through light barriers such as doors and thin wooden walls before detonating. A mix of HEAT And HE-Frag might be carried by the Shooter other members of his unit.
A High Explosive round would be a basic thin shelled warhead ( the roughly cylindrical warhead in the pic) filled with high explosives ( of course )designed for destroying structures or taking out reinforced bunkers and light vehicles.
Carryng a mixed bag of rounds might complicate supply and logistics a bit. So some militaries might decide to make due with just the standard warheads.
