Gaiaterra: Elysea's Conflict/Desolator Fuel

When the Elsword Empire split off from the Voshkod, they made it very sure that they destroyed any and all of the Voshkod's data on their nuclear technology, from burning down every laboratory that even had an inkling of it to destroying every Super Reactor leading to massive, fallout-filled, "dead zones" and killing every scientist that wasn't there's who knew of it. And with their success the Voshkod had basically lost both their most powerful weapon and electric power. And scrambled to find a solution to regain the power they lost.

Turn to power researcher Runolf Heart. Who began working tirelessly with what data they could salvage (which was pathetically little) eventually led to the well-known (and hated by the Guardians/enemies of the Voshkod) invention is his Kalach Compound, a thick green substance (derived from mixing various toxic compounds with help from the data). And when the first Super Reactor lit up, and showed to have the same power as their lost Nuclear reactors the crowds cheered and christened him a saviour. But a few weeks later the compound runoff was drained to a nearby field. Minutes later, people couldn't enter the green, desolate fields, as their shoes melted and they quickly became very ill.

Heart ignored this and went to other projects, but the Red Army quickly took the compound for its own uses.

History of Use
The Red Army quickly conducted tests of its own, which showed that the compound was so lethal and corrosive that it could strip flesh off the bone, and would dissolve through the bone mere seconds later. In addition, the compound, when not used, was shown to be extremely toxic and almost certainly lethal for a person should they inhale it or come into physical contact with it. Heart's Kalach Compound, and its runoff, was found to contain over a dozen different corrosive and poisonous compounds, all of which were lethal to organic life. The results were immediately classified and hidden from the Voshkod populace (to preserve Heart's reputation, of course) and the Army saw potential in its use as a weapon.

The Kalach Compound runoff was (easily) weaponised and dubbed the Desolator Defoliant. The Red Army mostly used it in bombs dropped by Tu-4s and Tu-95s and later Tu-160 bombers to deny land to Guardian forces. It is also used to clear buildings of fortified troops, though using it on civilians is against several Voshkod and international laws. The Voshkod have been able to develop biohazard gear that doesn't melt into uselessness upon coming into contact with the Desolator Defoliant, and specialised infantry units have been equipped with Desolator Defoliant. These Chemical Troopers have been employed in battle to horrific effect. Also, tanks of it are built under the ground of Voshkod bases and linked to hoses used to fight off attackers, which can be used by men or as a Desolator Tower. Recently, the Voshkods have developed a new warhead loaded with Desolator Defoliant, for use with V4 rockets and Topol-M Missiles with Desolator Defoliant. Naturally, the Guardians protested vehemently upon learning of this new development.

Lysenko made a formal suggestion that inmates from insane asylums and particularly troublesome gulag inmates be put in armoured life support suits armed with hoses full of Desolator Defoliant (for use in clearing underbrush ahead of tanks.) His proposal was denied by everyone but the Gorizont Division (much to the other three's disgust), who saw it as a good way to use the Defoliant. With the rest putting [REJECTED] stamp covering every square centimetre of the proposal (including the blank sides).
