Old ground I know but if you don't practise with the complete weapon system in peacetime it is unlikely to be with you in wartime.
Going to war with a logistics, armament and engineering system that is untried and assumed will leave us with a willing pilot but precious few aircraft when peak demand comes around.
Why old ground? Well once we stopped regular independently monitored TACEVALs we decayed to the point where justifying trades (eg armourers etc) became increasingly difficult to the point where squadrons were simply not capable of performing on actual ops as a unit. Pulling the true required strength from non-deployed units to enable those actually deployed on ops to function became the norm. Even a bunch of us simple aircrew types started to realise that a more major conflict would leave us gutted of actual capability. The complete weapon system is much more than pilots playing in a synthetic universe.
So here we are, hoping that the support tail actually knows how to support multiple squadrons of aircraft that are hardly ever flown, with little maintenance and engineering practise required with 'combat readiness' stats being produced by the latest thrusters based on algorithms and modelling only fully endorsed by the bean-counters. Aircraft will spend many days or even weeks without being flown, being listed as 'serviceable' right until the point where you actually prep, fuel, arm and start the thing.
God help the frontline when they try and fix and turn an aircraft for a subsequent wave without loads of other not-due-to-fly-anytime-soon aircraft around them to either reach for or rob from. And you really have to pray for the trades that may have never undertaken their core role on a real flying aircraft under real conditions.
We live in a tactical universe where simulation has to augment peacetime flying. It has become an essential addition to the workload of frontline aircrew. We will bitterly regret allowing the augmentation required from simulation to becomes a replacement for the core business it was designed to support.
