Chuck,

in "Entering Germany" Tony Vaccaro talks about his Army time in the late WW2 - he enlisted as a photographer and accompanied some infantry troops (IIRC).

In one chapter he talks about how he processed the films he took with his Argus - he used a tent and dunked the film in steel helmets.

Ok, back to topic.

No, there is no washing agent that may be used in place of water. IIRC there was research on super stabilisators in the early 1990s, but it was a dead end.

I use the Ilford method for washing films, it is safer/more archival than flowing water. Actually this is the "Agfa method", they recommended it since the 1950s for the Rondinax.

If you need to speeden up the drying process, you could use ethanol - dunk the reel in it for a minute, let the emulsion soak the ethanol and hang it. it will be dry in a few minutes. Perhaps you should rewash it later when you are back home... just to be sure. That method usually was applied by press photographers who didn´t care for archival processing... but for speed.

Tetenal has a ready made bottle of this stuff - "Drysonal". Expensive Ethanol. ;->

To cut washing times you need to speeden up fixing. Use a two bath fixing (>always fresh fixer, always "clean"), keep fixing times short (double/triple clearing time) , add a soda bath (20g sodium carbonate per liter) after that and you may save a bit on the watering step.
