Sorry but whats the use of a lance if you use/grab it overarm like a javeline?
if you take a look at the pictures above
overarm (like a javeline)
means like you can see in the picture that you carry the lance over your shoulder.
that reduces the range of the lance by almost 50% because you have to grab it in the middle ....
(you loose 1 or 2,5 Meters range depending on which lance you use)
you can only stab downwards and only at enemies that are very close in front of you
because of the anatomy of your arm/hand
it is also much more exhausting to carry a lance overarm
a attack is much weaker because of your anatomy
you can't defend yourself against cavalry! (again because of the anatomy)
underarm
easier to attack and you have more attack power because you can put
your own weight/mass into the attack
it is easier and less exhausting to carry a lance underarm because
your underarm supports your hand (lever)
you got a higher range because through the support of the underarm
you can grab the lance closer to the end.
useful against cavalry because you can easily and very fast put the end of the lance into the earth
and raise the lance against the attacking cavalry.
by raising his arm up to his shoulder the guy behind you can also use his spear (spearwall)
I haven't read and don't know this Osprey
but I guess this guy never tried to fight with a spear/lance
because if you try to you will for sure use it underarm
because that gives you much more fighting possibilities
especially if you are in a close formation
