Russians Use Improvised Bridge-Laying Vehicle to Cross Kazennyi Torets River Near Pokrovsk

If air defenses play the role of linebacker in land war and artillery the quarterback, bridgelayers are the core of the wide receiver role.

Why is Russia "improvising" bridgelayers and deploying them with such sloppy tactics? What could possibly be more important to build according to a design process and utilize with intention than bridgelayers when your objective is to take and hold territory with armored forces?

It is desperate is what it is.
