As UK political leaders are urged to hold a 'frank conversation' with the public about wartime preparations, historic rules show that medical exemptions could allow some to avoid fighting if conscription is reintroduced.
General Sir Roly Walker told Sky News that 'every' citizen will be 'asked to make sacrifices' and play their part in the defence of the country. This follows escalating tensions between Russia and Ukraine, with President Trump appearing to align with Russia, urging Ukraine to remove President Zelensky and penning a deal with Russia for diesel.
Historic Precedent from World War Two
Conscription was introduced in May 1939 to prepare for Nazi Germany's expansion across Europe. Under those rules, men were given a medical assessment before being sent to the front lines, and those found medically unfit were exempted from fighting.
According to the UK Parliament website, those medically unfit were allowed to complete important wartime jobs instead. It said: "Those medically unfit were exempted, as were others in key industries and jobs such as baking, farming, medicine, and engineering."
Current Conscription Rules and Age Limits
The government is increasing the maximum age for calling up "strategic reserves" from 55 to 65. Ministers have said the UK needs to be prepared for 'war in our homeland', with a greater push to ready society for conflict as well as national emergencies like pandemics, extreme weather, and cyber attacks.
A UK government report issued in March 2025 explains how conscription works in other European countries. It says: "Most countries obligate men to serve, offering opportunities for women to volunteer if they wish. Many also offer an alternative civilian option for conscientious objectors. Some use a lottery model, meaning that only a small proportion of eligible men are required to serve."
Conscientious Objectors in Europe
The report adds: "The European Parliament’s research service briefing on mandatory military service says all EU Member States with an active conscription system have recognised the rights of conscientious objectors through national law."
For example, in Finland, males are mandated to serve by law, but non-military service can be given to conscientious objectors. In Greece, the minimum terms are: "Less than 12 months military or 15 months civilian service for conscientious objectors."
