So a few notes 1 I am using fictional attachment names and using fictional calibers so Americans don't kill me please 2 this is my take on the lore not heated chocolate or dustrons if they deem it implausible then I will delete this 4 there will also be guns I suggested so some of them won't be in there.

K3A3:The standard rifle for non-conscripts it is based of the k2 BR rifle which is a old federation the k2 it's older BR rifle cousin was adopted by kestrels as a BR after the federation retired it for the RK5 ,the K3A3 uses 5.56 instead of 7.62 as it is a standard infantry rifle and not a BR rifle

RKD 55: the RKD 55 is a modified version of the RK47 so it is more modern and can compete with other guns on the battlefield it has also been modified to be more rugged and light,because of these modifications it can afford to use the heavier 7.62 round. It is not to be confused with the RK5 as it is another weapon platform

RHINO LCW: a copy of the Keller 45 and Keller 9 it combines elements of the 2 SMG to be a balanced SMG tho it is heavier than normal SMG'S causing issues,to combat these issues it is more commonly being chambered in 9MM but that to has issues as it takes away from the power the SMG had which made the grebes choose it,because of these issues there looking for a replacement

KAVALER MP49A1:the most modern gun in the is a pistol. All jokes aside it is the most reliable pistol and is popular with civilians even some kestrels take it from dead soldiers and replacing their standard issued taros with them which mind you are actually a rip off of another pistol,tho there is a big downside which is there's no full auto kits which make snipers looking for a CQC sidearm useless because of this snipers steal taromatiks from dead enemy soldiers others just bring a rhino into combat.(in 9MM)

NATIONALIST 7.62:this is a ultra reliable AR/BR rifle that was in use by the union for a long time before replacing it with bullpup AR'S more country's that still use it like the albatross armed forces give it a upgrade. But the grebes didn't give it any attachments or modifications other than a scope. For some other info about it is that it can be chambered in 7.62 or 5.56 CROCUS squads use it with a clip tug stock and green barrel and stock and internal suppressors along with 7.62 and ACOR optic,the albatross Grenadiers use the A2 variant with a grenadier barrel and rearstock along with a ARCO optic and grenade launcher,tho ol'reliable has competition as upgraded variants are being fielded like the countryman and the patriot

K3A2:I don't have much other than it uses 7.62 and fires slower but hits harder and it is a updated version of the k2
