Not that uncommon
My company makes electronics and computing that goes in planes, tanks, helicopters, ships, rockets, etc. A support call (usually to the force's local logistics hub) can start in a very benign situation, that very quickly becomes hostile. The squaddies are so used to it all that they will often just carry on unless in mortal danger (especially if it has been hard to get the call through in the first place).
Given the amount of our stuff that goes into space, some of our staff do note that there is no on-site support for off-planet equipment.
Anonymous, as we like to keep our heads down out of the firing line.
