BBM? Abbreviation has stumped me.

[kato13]

I consider myself knowledgeable on the Russian military compared to the average news reader but this has stumped me.

Even context clues have failed me. - Raymond Holt

Russia lost 14 planes, 8 helicopters, 102 tanks, 536 BBM, 15 heavy machine guns, and 1 BUK missile since Feb. 24, according to Ukraine’s military.

It is not in this. (Frist google result to a reference material)

Any thoughts? Internal Ukrainian nomenclature perhaps as they all seem to come from casualty estimates from the Ukrainian govt/military
