I agree with
almost everything posted. I would add a
foraging, which would be the acquisition and use of essentially unpalletable foodstuffs for survival. Not the same as wilderness survival, and not as generally useful.
TL 3 armies can field arquebus and other smoothbore musketry.
An arquebus is a matchlock, TL2 in CT, always smoothbore. :nonono:
TL 3 is the flintlock, which could be rifled or not; early TL 3 armies thus were armed with the (unrifled) muskets with socket bayonets for the rank and file, while a few snipers / skirmishers / irregulars would have "rifles," or rifled matchlocks. In 1860, the Minie ball was invented, which had become commonplace by the civil war, aruably the dawning of TL4. The metalic cartridge (rerequisite for revolvers and shotgun close to how these are defined by CT) was available, but not widespread.
Thus at TL 3.5, or so, the standard was "rifled muskets," a bastardized term that originated with the practice of riflling existing smoothbores for the minie ball. The originally manufactured rifled musket, with a "cap lock" and firing a mine ball proliferated towards the end of TL3, but before the proper centerfire metallic/semi-metalic cartidges in revolvers and shotguns which would mark the beginning of TL4.
Thus, since any professional officer in a Napoleonic-era army (and arguably the professional armies of the latter 18th century) who did not know what a "rifle" was would have been laughed out of the mess, I would state that a TL3 soldier may well have been familiar with the "rifles" of the day, rifled flintlocks, serving as either rifled muskets or as "rifles."
Since the ballistics of these required different skills than smoothbores (i.e.: marksmanship), which is 90% of the difficulty of expertly firing a rifle (been, there, done that..), then I would say that a TL3 soldier could get "flintlock," which should function as "rifle" of one skill level less on a throw of 7+. In the alternative, the skill could either be designated as "smoothbore musket" or "rifled musket."
The real issue is whether the army is TL3 or TL3.5. Though canon makes no distinction, the reality on the ground was night and day for infantry small arms.
