My idea is to keep it rather easy on the eyes of non-gun nuts like myself (some coaching will be welcome). But to answer your first question is: yes,  a lot of witches would use guns if they could, they are just power drunk, not stupid. That being said, there are not that many due to how they went overboard with the destruction (remember, power drunk) and lost the means to acquire weapons (with the notable exception of South Africa)

Also the rule of thumb for enchanted weapons (that is, MUW), is that the more complex the weapon, the more difficult the enchantment, so yeah magical shivs and pointy sticks are the most common. (They also can be made with pre-industrial revolution methods).

[@Jasper19]Troopers can be medics but probably they can only afford customized uniforms if they are from Sydney. Magical healing is definitely possible (and sorceresses are encouraged to learn it) but it remains a critical asset (like yhe rest of GRAM sanctioned magic) and won't be used willy-nilly.

The choice is possible. But they would be criminally accountable (if applicable), have a killswitch implanted (like the rest of sorceresses) and shunned by most of their peers (for the same reason). Whether canned food, hot water and toilet paper (along all modern commodities) are a fair price for the loss of freedom is up to the individual.
