 When embodied, the Territorial Force, and its members, were liable for service anywhere within the United Kingdom, but could not be ordered out of the country.However, it was provided that any part of the Force, through its commanding officer, could offer to subject themselves to the liability for overseas service, or to be called out for military service within the country for defensive purposes even when the Territorial Force was not embodied.The Act took pains to ensure that "A person shall not be compelled to make such an offer, or be subjected to such liability ... except by his own consent", and required commanding officers to explain to every man that the offer was purely voluntary.
