1) Air to land rockets usable by our bombers and that old cheap triplanes
2) Mountain howitzer
4) New mortar
5) RPG-2. Larger caliber, longer range (Bonus: will help to get +1 ore for 3 turns)
6) Nimble air-superiority\strafing aircraft to clear the skies and let our dive bombers bomb more easily. + strafing enemy in narrow mountain passes
You obviously haven't been paying attention. The battle reports have stated multiple times that artillery is either useless or significantly less useful than small arms in the Mountains. Our planes and mortars have had only limited success in the Mountains at any point in time while any new advances in small arms has been a great success for whoever made the advancement.
3) 20*100mm heavy sniper rifle to outrange their sniper rifles
We don't need to outrange their sniper rifles, we just need to be more accurate. Moreover, a 20mm sniper rifle is way,
way overkill. What you're talking about isn't even an AM rifle, it's an AT rifle. It's of limited usefulness against tanks but not infantry, especially considering the enemy's ability to suppress us.
7) New 12*100mm machinegun (bonus: can help to win the expense credit if we manage to keep it cheap)
Like our 1910, it would be too heavy to use in the Mountains.
Glory to Arstotzka.
You're saying their cheap Cascade was actually useful? But that's impossible! Aseaheru himself said that revising our MC16 was a massive waste of time with no tactical benefit! Shit, if only there were someone around here who could've told us a cheap SMG was useful all this time.
It wasn't the cascade, as that one never became expensive. It was the rest of their automated weaponry.
IMoskurg still makes very prolific use of the Cascade, and has an advantage in infantry fights in the jungle which tend to be at close-medium range.
Exactly how many direct battle report quotes do I need to submit before the usefulness of the SMG becomes apparent to you guys?
