I love it.
"nor was overly-enthusiastic engagement of non-targets such as migratory birds and rain squalls."
I can sooooo see that happening with a kludged up system like that.
But on a more serious note, Engaging ATGM's? I can buy that, the system was designed to shoot down missiles after all. I can easily see a commander placing one in and armoured assualt with a mission of intercepting incoming missiles, at least till the sovs learned that the slugger needs to be struck out asap.
