Maybe it's helpful just for you to understand the way the military is organised: if you are conscripted you should report to this base, you'll sleep here, your commanding officer will be someone from this branch of the armed forces, you'll be in a group of X people sharing Y shifts, etc.
I do competitive bullseye rifle, and I've done some basic marksmanship coaching. That's about what I'd expect for maybe 6-12 hours of total training on a rifle for someone with zero prior experience with guns.
The basics of rifles is very, very simple. In competition world we just get overly focused on stuff that doesn't matter - our benchmark is like 10/10 shots at 400 yards in an 8" circle. For someone getting basic instructions, 5/10 shots at 400 yards in a 16" circle is probably fine, and that is an order of magnitude easier to teach.
It took me like 3 hours from zero experience to get to that, and another 300+ hours to get to competitively decent at prone (I might be good now but I'm not particularly skilled so it took me a lot of practice). And we're not going to talk about standing because in the competition world what we do is so far removed from reality that it's not worth talking about in this context lol. Someone with run&gun experience can talk about that, I don't know anything about that.
This may be true but we want any adversary to think that we will! We at least ought to be all able and willing to do so. I hope our generals and military command know better but I want them to have multiple options and I want any adversary to have to think twice before breaching our shores.
it sounds like basically if the country was ever in a situation dire enough that they were calling on ordinary citizens to help with defense, an ordinary citizen with a week's training would be better than one with no training.
or more cynically: it's a way to make a whole bunch of voters feel like they're involved in the military, to make military spending more palatable to voters.
