Bolt-action rifles are often disregarded in this game and shamed as useless. However WW2 was not fought with M2 Carbines and Stgs alone. Bolt-actions played an incomprehensible huge part and were the backbone of every single country (except America). Every weapon type has its place on the battlefield, from your bolt action all the way up to assault rifles.
Germany probably had the largest variety of bolt-actions from all their occupied territories, but regardless every faction has its share of bolt actions that could be added to the game.
Point is don’t let bolt-actions be left in the dust. New bolt actions could be added as some neat Premium or event squads, event weapons, or just as regular unlocks in the research tree for flavor. Not to mention just like many other weapons, there may be variants as well such as carbines, long rifles, snipers, rechambers, etc
Here are just some bolt-actions that could be added:
M1903 Bushmaster Carbine, Springfield carbine designed for jungle warfare, named after the 158th Infantry Regiment who used the rifle for training while stationed in Panama who later did see combat in the Pacific, could be a Pacific premium/event squad
Kar98k Paratrooper, experimental take-down variant that was designed for Paratroopers, similar to the Japanese Type 100 Para rifle, could be for a new Paratrooper squad
Lee-Enfield No. 5 Mk I “Jungle Carbine”, made in Britain, shortened carbine of the Lee-Enfield No.IV Mk I, was designed for British forces in the Pacific BUT only saw service with some Paratroopers in Europe, got the nickname “Jungle Carbine” for its service in Asia AFTER the war, so I would say it could be for a new EUROPEAN British paratrooper squad
Lee-Enfield No. 6 Mk 1 Jungle Carbine, developed in Australia, shortened carbine of the SMLE Mk III, it was intended to see service in the Pacific and was almost formally adopted but the war ended, this should only be in the Pacific campaigns
