Russian media released drone footage showing the destruction of multiple US-delivered M777 howitzer artillery cannons.

While the M777 isn't necessarily a high mobility system, its relative lightweight allows it to be put into and taken out of action in a few short minutes, which would allow the Ukrainian gun teams to continuously operate from new firing points without being located. However, the pile of charge cartons shown in one of the clips suggests that these teams remained in a static location long enough to be detected and destroyed.
