Video released by a Border Guard working near Kharkiv shows the use of an improvised munition made from discarded soda cans and cardboard being used against Russian fighting positions.

It's unclear what kind of explosives are being used in this improvised explosive, however one would guess that they're using military grade explosives and not the homemade explosives we saw in places like Iraq and Afghanistan.

This video was released by a member of the Ukrainian Border Guard conducting defensive operations near Kharkiv.
