In Hearts of Iron IV (HOI4), Intervention Forces are military units that can be deployed to other countries to support their war efforts. These forces can be recalled at any time, but doing so will incur a diplomatic penalty with the country that they were deployed to.
There are several reasons why you might want to recall Intervention Forces. For example, you may need them to defend your own country, or you may want to redeploy them to a different country that is in greater need of assistance. Whatever the reason, it is important to be aware of the diplomatic consequences of recalling Intervention Forces before you do so.
