tactical needs and strategic needs must maintain a balance.
This isn't the case here. The US occupations of Afghanistan and Iraq were always deeply confused as regards what the strategic goals were supposed to be, but now that only international air units and a few thousand advisors remain, there isn't really any strategic goal at all beyond "we're still technically influencing events in the country". As such, the only tactical goals there can be are to continue to poke at the Taliban while preserving the lives of what few Americans are operating there.

In other words, when you're just going through the motions, you get cases of thoughtless negligence like this in which no one considers the possible consequences of a particular mission beyond the next hour because they become immaterial to 'whatever-it-is we're supposed to be doing'.
