This combination of mounted camera and drone footage shows a Ukrainian BMP-1TS using its 30-millimeter cannon to cover troops attacking Russian trenches. The BMP-1TS is a BMP-1 that has been upgraded by a private Ukrainian company known as Techimpex.The chief improvement to the 1TS over the base model is a drop-in Remote Weapon System that allows for more accurate, stabilized fire. Note that this is a relative term- the work shown here appears to be much more "to whom it may concern" than a Bradley's 25-millimeter version of specific address. Ten of the 1TS version BMPs were unveiled by Ukraine in 2021; one was confirmed lost during the Russian invasion the following year, with the remainder being rarely used.
