Obsolete troop types

[Sinner]

I don't know if the troop types are all that matters. tactics is another thing. In Napoleonic times, infantry can easily defeat cavalry while in square but would be soundly trounced if in line.

That would depend if the infantry are lined up ready to fire with good officers to get the timing right & disciplined troops who obey their officers & hold their fire until ordered - in which case the footsloggers will be eating horsemeat steaks for supper. The cavalry should counter by pulling away & starting to try & flank the infantry, but then the infantry can counter that by forming into a square, etc.

combined arms can thus present the enemy with a dilemma of facing superior infantry fire to lose the missile duel if you are in square or risk getting charged down by cav if in line.

Combined arms is always the way to go where possible, artillery plus cavalry were death for the infantry... for MTW, I'd guess archers plus cavalry would be more appropriate.

It's been said that the pure slowness of a Biplane would pose a difficulty for modern air2air aircraft. Or maybe it was difficult for heat seeking missiles to track a biplane.

The slow speed would be a big problem, but since modern fighters can and do shoot down helicopters which have similar top speeds to WW1 biplanes it wouldn't be impossible. Not too sure about the heat seeker, since they are effective against modern piston engined aircraft, but I'm not sure if the weaker engines used on WW1 biplanes have as strong an IR signature. Same for radar guided missiles, although modern ones are designed to be able to track low radar signature targets. Not that it matters, because a peasant would have already brought the biplane down with his pitchfork.
