What means MTLG

Hi all.
I download MTW Building and Unit Data.
I don't understand - what means MTLG in Prjtl Type column.

Thanx, Max Salimov

I think that term is carried over from STW.

MTLG = Mounted longbow.

which was refer to the bow used by Mongol Light Cavalry (Mongol horse archer).

In MTW, I think it still refer to the bow that cavalry use, but it is not the Longbow as the one English Longbow use.
