Different industries prioritize different things. I'm speculating but being the military they may consider that the enemy is planning an incursion exactly when some critical detection systems are expected to be down. So they'd rather kill some equipment while they mobilize a contingency measure. No idea what was in the manager's head or if the threat model makes sense but things aren't always super obvious and don't lend themselves to generalization.
