Dear Civilian puke: I mean no disrespect of course-you cannot help being ignorant, becasuse you are a nasty LEG. (a non paratrooper) Naploeonic muskets were smoothbore weapons. What is a rifled musket you ask (in ignorance)? By the American civil war rifling had been introduced which greatly increased the accuracy of these otherwise (still) muzzle loaded weapons. A well trained riflemen of that era could fire perhaps three rounds per minute. Many Civil war Generals who had dutifully studied Napolonic tactics were rahter slow to catch on to the fact that this rifling of the muskets barrels produced a much greater "effective" range.
Note: they did have breech loaded carbines but they were not in widespread use until late in war, except by Union Cavalry.
I do not have time to educate you on tactics. Suffice to say however; that barring someone of limited imagination or intelligence (such as Nasty LEG) being placed in command of a force of paratroopers-the musket equipped force could not hope to prevail either in the attack or defense.
Paratroopers of even WWII were better equipped and trained than you apparently realize. Modern paratroopers ...well lets just say that I'd be willing to test your theory. My old unit B Co 2/504 Inf/ 82nd ABN DIV against you and a force of musket equipped men of even ten times our number. Fortifified or not.
Regarding infantry throwing grenades down hatches of tanks.
Surely you are not serious. You have obtained your knowledge from hollywood perhaps...
Tanks (in anybodys army) usually work in concert with infantry.
(By the way you can lock hatches) It is true that in restrictive terrain (ie dense woods, forest urban environments etc..) armor is vulnerable to a variety of measures to incapacitate or kill them...but I find it difficult to believe that musket or spear equipped infantry would do much more than wet there pants sat the sight of oncoming armor.
