I think every military is having recruitment challenges, starting with the fact that the numbers in the desired 18-25 demographic is at an all time historical low. Physical and medical fitness are also lower than ever. That being said it is still far from a crisis.
IMO the real challenge will be if the institution learn the lessons from Ukraine. The first big one is the fact that era of traditional land maneuver is over. The second big one is spending on building materiel capacity. This means cutting back on the bling in favour of buying lots of boring but vital ammo stocks and repair items.
Finally the theory of an information connected land battle space is now not theoretical anymore it is now non optional to achieve mission success. This has huge implications on doctrine for all three elements and the associated training and equipment.
