“Found these in the Zaporizhzhya direction. The enemy is throwing chocolates with an explosive mechanism. Do not open them under any circumstances. Our guy was lucky that it did not detonate, otherwise he could have ended up crippled. I know guys whose fingers were torn off like that.”
I agree the round disc and deliberately folded wire screams something to do with RF, but a) how powered and for how long? and b) why a chocolate bar if so?
It’s not like they hid a transmitter inside something that wouldn’t be taken apart or eaten, this was going to get discovered. Sneak a transmitter inside a PKM or radio, then let it be “captured” by the Russians.
The wire in the middle is bent and acts as a spring. The metal disk on top slaps the tan paper on bottom when the wrapper is removed. No power, all mechanical.
Might even be passive, a tuned resonator. Heck it could be a bug, IIRC ironically passive bugs are (age-old) soviet tech. Imagine sweeping the whole frequency spectrum for resonators with 50s tech they were a nightmare to screen for.
Maybe the idea is to track people for some time to gather intelligence on trench operations? Most probably aren’t going to eat the thing right away.
