Russian tank crews resort to DIY armor in response to shortages
Due to a shortage of reactive armor tiles, Russian tank operators are attempting to create them in field conditions. We explain how they do this and whether it could work.

Reactive armor tiles are crucial for Russians to protect tanks from handheld anti-tank weapons or FPV drones with single-charge PG-7VL anti-tank grenades. However, it’s worth noting that newer anti-tank solutions with dual-stage warheads can overcome older single-layer reactive armor without much difficulty.
As shown in footage from the front, the Russians are not producing enough reactive armor tiles, and some tank crews are making them themselves in field conditions using available materials. Below are pictures from the production of such improvised reactive armor tiles.
A Russian spreads plastic explosive material from a UZP-77 mine-clearing charge onto what appears to be a copper plate and then uses a hammer to attach another metal plate, creating a sort of "explosive sandwich."
DIY reactive armor tiles
The Russians have published schematics of Kontakt-1 tiles online and called for their mass production by any private company. However, their assembly by tank crews at the front line represents a new level of desperation.
Structurally, old-type reactive armor tiles like Kontakt-1 are straightforward since they are just basic steel plates filled with very stable (hard to detonate) explosive material that only explodes under specific conditions.
The purpose of reactive armor tiles is to prematurely detonate a cumulative warhead while dispersing the cumulative jet through the shock wave and fragments resulting from the tile's detonation. The name reactive armor comes from how it functions, i.e., explosive reactive armor.
For example, it can stop a PG-7VL grenade warhead capable of penetrating 20 inches of steel armor with a combination of, say, 4 inches of armor and a reactive armor tile. The main armor must withstand the tile explosion, so it cannot be used on anything like mounting on UAZ "Buchankas."
However, it’s important to note that production requires suitable raw materials. Not every explosive material suits this (TNT is a wrong choice), and the assembly process must be precise. In the case of severe material shortages and production errors, such as gaps between the explosive material and the plate, it might result in a cumulative warhead instead of creating a protective tile.
