Its not the Zerc fitting, its the bearing seals where the shaft comes 
out. You can get water inside the dust and grease seal. Believe me.

Depends on the tank and the transmission. Some things have T handles 
(handle bars) like M114s and M1 Abrams. Some things have brake levers 
(2 pairs, 1 pair is a set of brakes for each side, the other is a set 
of direction levers for neutral steer, etc). The Universal Carrier 
has a steering wheel that moves a rod that moves road wheels or the 
front idler (can't recall) and at the extreme end of is travel (thus 
warping the trcak in a certain direction) actually stops a side from 
turning.
