The grenades we just did. Those are CQC weapons.
They're not primary weapons. Given the choice between going to battle with only an SMG or only a pair of grenades, a soldier will choose the former.
Expensive equipment can be given to officers, or one per squad (5-10 soldiers)
Thats about the levels that SMGs are used in the military thesedays. One per squad.
This is vague. By "thesedays" you could be talking about our RL present or the current in-game date.
If RL: What we use now is irrelevant. Different times call for different approaches. What works in our time won't work in Arstotzka/Moskurg's time. IRL we have other CQC automatic weapons to use besides SMGs like the M4A1 (assault rifle carbine). The battle report (the thing that overrides what we
think is important and tells us what's
actually important) said that more SMGs are better and that means we should get more SMGs.
If in-game: That is a bad argument. That's like saying "We don't need cheap Nosin Magants because we have Expensive Nosin Magants" back in the beginning of the war. We needed cheap Nosins. Saying we didn't need cheap Nosins because our Nosins weren't cheap just doesn't make sense. Neither does saying we don't need cheap SMGs just because we don't have cheap SMGs.
Well, except special squads, but since the quote you gave talks about a squad of just SMGs...
Three. In. Five. Three in five men should have SMGs while the rest have other weapons,
based on the battle report stating that that was the optimal number of SMGs that should be fielded. Getting our entire army to field nothing but SMGs is stupid and I would've thought it was obvious I didn't think we should do that. Being
able to equip every soldier with one is what I suggested, not because we
should but because then we'd be able to equip as many as we
needed.
