@Didascalo well you seem to be very knowledgeable in the matter of firearms. Honestly I wasn't aware how it was viewed the IA2.
AFAIK most of the Brazilian military is OK with using their current equipment and vehicles, but even the guys I know in the Brazilian Armed Forces complain that both haven't been updated since the mid 1980's, which you think would be a priority considering that crime has gone up in most cities and states because until recently public safety and violence seemed to be a secondary issue for most governments...
Are you perhaps Brazilian or just know a lot about guns?
Guilty, I'm Brazilian and a firearms fan, what happens on the military is just a fraction of the real gun "state-runned" industry, that happensfor examplebcs the State of São Paulo has 44Mi habitants (pretty closeto france) and more them 230.000 active men in their police force (here called the military Police) and they use the same standard equipment as the army (that happens to have a little bit more than 300.000 active members), on the vehicle and tech development side, Brazil rathers spent their money buying tech fromtheir allies and producingMilitary Frankenstein's like the Guarani, a light Blinded assault vehicle that can be modulated to use Anti-Personel, Anti-Tank and Anti-Aircraft weapons according to necessity, if Ihad to define military research in Brasil with one word would be... Adaptable, because the creativity to use the same equipament for 4 or 5 functions makes an outstanding difference specially considering the low number of carrer soldiers (Less than 200.000) that happens becausemore than a third of the active military is compulsory by the age of 18 and can´t be followed as a carrer, so every year, new soldiers come and need to learn everything and them go out in 1 or 2 years (pretty bad system if you ask me) as a result, wedon't have many specialized units, every branch of brazilian military is a joker card, and a had full of jokers is bad as fuck hahaha.And about the governments and their Defunding of the military, At the 80's Brazil came out of a military distatorship (I know, pretty south american) and ALL the governments that came after thta were heavily anti-military since 2002 Brasil had 4 presidents, 2 of them fought in communist militias and were arrested for armed confrontations with the dictatorship at the time (the were also very corrupt and destroyed the economy while there, but that's for other day), the only government since the redemocratizaon that supports the army is the current one (since the president was a military carreer captain) but he sucks too...
Sorry, i got carried away,oh about the violence, it is pretty bad in most places but the stats are broken, when you compare São Paulo (13 Homicides by 100k residents) with Pernanbuco (49 Homicides by 100k residents)you have a 31H/100k residents ratio by state... and as you can see it's not very accurate, never trust numbers given by governmets, at least in Brazil, i don't, the deep state is powerfull here and perpetuating power is the only political agenda...
Sh*$ got carried away again, none of those answers are easy though, i hopei helped, anything else you need, don't mind to ask
