This Russian says to unscrew the striker screw to disarm the Ukrainian “Gingerbread” improvised anti-personnel landmine. If his comrades follow this advice it will likely push the screw into the primer as the thin printed casing flexes, and blow both their hands off.

Footage of a Ukrainian soldier recovering high explosive filler from an undetonated 500-kilogram (1,100 lb) Russian glide bomb.
The mechanism of an AK magazine booby trap found in Bosnia 1995 is described in a nicely done animation. The video also serves as a clear explanation of the functioning of the Russian MUV-4 fuze.

The Russians call this new Ukrainian improvised anti-personnel landmine “Soapdish” (Мыльница). Dropped by drones, the printed device has a spring-loaded striker restrained by a winged pin. Compressing the case forces out the pin, releasing the striker into the detonator. 1/

This Chinese contact wire impact sensor for FPV warheads has an electronic arming switch with a 30 second delay. In video 2 similar “whisker” contact wires project ahead of the FPV bodies. When the separated wires touch, an electric circuit is closed to initiate the detonator.

The Russian “KOZBCh-1.8” (КОЗБЧ-1.8) is a new 1.8 kg FPV warhead. Similar to the “KOFZBCh-3” in the quote, it is apparently a shaped-charge fragmentation incendiary munition. The “P-795” (impact?) fuze is also new.

🤭🔥🇺🇦Ukrainian soldier throws a 120mm mortar shell into the basement with a Russian invader who refused to surrender. It's something new... before there were grenades and anti-tank mines, but not mortar shells 🤯
A Ukrainian piezoelectric impact FPV fuze for a PG-7M. The piezoelectric effect is when certain materials such as quartz generate an electrical charge under mechanical stress. This charges a capacitor, which discharges to an electric detonator when a voltage threshold is reached.

Ukrainian remote detonation kits in a plastic case or sealed tube are intended for control of explosive devices defending positions or dropped by drones. The remote controller has a directional antenna, can use repeaters, and can query the status of the device. 1/

A Russian drone bomb kitchen melts TNT from a TM-62M anti-tank landmine to fill printed bomb casings. The grey color indicates PVV-7 high explosive is probably part of the mixture. The fragmentation elements appear to be electrical box knockouts.

A printed Ukrainian HEDP (High Explosive Dual Purpose) shaped-charge FPV warhead. The concave metal liner will form an EFP (Explosively Formed Projectile), while according to the Russians the small birdshot fragmentation elements form a dense, destructive pattern.

A new Russian drone bomb “OPBCh-1.4” has been recovered. It is apparently a 1.4 kg fragmentation ring bomb last heard of as in testing and development, with a mechanical impact fuze. The ancestor for this device is the OFSP family, developed before the invasion.

A Ukrainian FPV has four control channels used simultaneously. The frequencies are 463, 952, 2278, and 2680 MHz. Such a broad range of frequencies will be beyond the capability of most Russian tactical jammers to cover.

⚠️For Your Situational Awareness⚠️ If you’re in an area where Shahed / Geran drones have been active, be aware of objects resembling the one shown below! This “cassette” element from the drone has been observed in multiple regions and they are designed to explode after a set…
A rare North Korean M1991 MLRS loaded with ammo was wiped out. A Ukrainian drone struck a shell, piercing the crew cabin and sparking a full ammo blast.
Ukraine has developed an airburst electronic fuze utilizing a laser time of flight (ToF) sensor or laser rangefinder. “Laser Deton” has a one minute arming delay, and 3 adjustable choices of detonation distance such as 0.5, 1.5, and 5 meters.

S. #Syria: Abu Omar neutralizes a large variety of war remnants (documented on his FB): Aerial bombs & submunitions, rockets-IRAMs, drone-dropped munitions, unexploded mine-clearing charges (UR-77), IEDs with fragmentation balls (he says most complex are from IS & Hezbollah) etc.

The 55 gallon drum was only popularized in the 40’s. First used by the axis, was so good at its job it was quickly adopted by the allies.

Ukrainian “Gingerbread” printed improvised anti-personnel landmines are perfectly camouflaged with fallen leaves. These small blast devices are dropped by drones on Russian pathways.
