Hubb mate, never make the mistake of thinking politicians care about the armed forces compared to other public services. I accept there is under manning in many regiments, squadrons and ships. So? They may be trying to aggressively recruit, and there will be many pinch points that urgently require resource to fill, but the govt priority will be towards rebuilding the economy, not the military. CV19 has, in the blink of an eye, changed the national landscape for many years to come.
And in any case, what exactly do you think the army will be doing in the next 5, 10, 20 years? Post Iraq and Afghanistan there will be no appetite to commit blood and treasure to military adventures that the country can no longer afford.
If you want to believe differently, mate, crack on.
