Interesting news from Russia. The Russian Defense Ministry has decided to annihilate the last reserves of gas masks for horses. These gas masks were in storage last 50 years and have never been used. These masks will be dismantled and all materials (rubber, glass, leather) will be sent for recycling.
During the cold war in the USSR were developed two types gas masks for the horses. The first type was used for short-term protection of the horse.
It is interesting that in the USSR gas masks were developed for dogs!
