Scrambler Lance: Projects a highly focused beam of light-energy on a target from long ranges, dealing increasing damage the longer it is kept on target. Most effective within its optimal focusing range, the Scrambler Lance can strike its enemies with molten fury from long ranges. Flashy; it catches the eye of every soldier on the battlefield.
While the Scrambler Lance has great range and accuracy, it makes up for it by having a low alpha compared to other heavy weapons, and reduced effectiveness against infantry in close proximity.

Plasma Mortar: A devastating mid-short range weapon, firing large caliber plasma shells at a slow rate of fire. Devastating to vehicles up close, and to infantry in close proximity, as each shell has a small blast radius from the plasma shell imploding upon itself. Its bane is open fields, as the powerful shells are wildly inaccurate. But what the Plasma Mortar lacks in range and accuracy, it makes up for with unmatched mid range power against vehicles.

no mortar implies indirect fire

probabally something similar to the PLC but for heavys
