If it's nuclear WW3 I doubt whether there is any time worth preparing for it - just say goodbye.
The methodical, systematic and professional training of the British military is crucial to the effective defence of the UK in any takeover scenario. Conscription would not cut it but we have to start somewhere and face reality. Successive Governments have buried their heads in the sand and actively reduced armed forces numbers. They have been reckless insisting on risking the military capability with equality and woke agendas which have no place in the real world or in the defence of this country. We are all at risk. Men are physically stronger than women but women can still fire weapons with equal efficiency. An armed forces team is only as good as its weakest link. It needs to retain its standards, proven over time with training and not weaken our defence capability with progressive ideas of an unrecognised minority.
It is time to start treating our armed service personnel with the respect they deserve, on pay and conditions, on accommodation and on support after conflict to help increase the numbers. Politicians have cynically used the courage of our armed forces to create their own vanity agendas. They are quick to sell them down the river. Those same politicians of the past might wonder why there is now a huge recruitment crisis.
We are also delusional if we think our current population can be fit enough to run for a bus never mind running across open battlefields in conscription? I guess we have to start somewhere? Getting an hour of physical cardio work every day for every student at primary and secondary school level would be a start?
