I can give a bit of context. Mandatory military service in Sweden only ended in 2010, so this is not a huge change.
During the cold was period, almost all men did ~1 year of military service. After that it was a regular job, but in case of war everyone could be conscripted.
By the '90s it dropped to maybe 1/3 of young men. Everyone went to a 1-2 day testing session, and then some were selected. In practice, it became increasingly voluntary. Soldiers on peacekeeping missions in foreign countries are all volunteers.
In 2010 mandatory service was dropped completely. I think the Swedish military found it difficult to recruit enough after that, and the politicians now think the military has shrunk a bit too much. I don't think it will be a huge growth (that would cost money), but perhaps a return to early 2000's level. This time it includes women.
I am not a big fan of conscription, but I can somewhat accept it as long as it's strictly defensive. One good argument for it is that a conscript army is unlikely to stage a military coup in a democracy. If the soldiers are more or less random people, they will more or less support the elected government, at least a portion of them. But, as military power becomes more about technology than numbers, I suspect this argument becomes less important.
