Ok we all have some reasons. I will explain mine. Some menbers like Mr. Faiez tolk of DMR as if there is one for each Rifle Platoon, but acording to the latest Portuguese Army TOE aproved, each 4 men "Esquadra de Atiradores" (Rifle Squad) will have a commander with a rifle and a radio, a "Granadeiro" (Grenadier) with a rifle with 40mm grenade launcher, a LMG gunner and a DMR. This makes a DMR for each 4 men team. My first vision was they would have a LMG and a DMR for each 8 men Rifle Section as many NATO use, but then they release this and I fought they would keep 2 G3 in each section (one for squad) and then release they will choose a new weapon in both 5,56mm and 7,62mm calibre. So probably it will be 2 HK416 (one with GL) + 1 HK417 + 1 MG4 in each team.
I still think they could have a G3 in each team, but the reality is that Portuguese G3 fought the African Wars since 1961 and for the most part are quite hold.
I just want to explain the racio of DMR we are talking!
