I always thought it was the same as low gear forward which was 9 MPH on the M-48s.

I believe that is correct for the M48A3-M60A3. Selecting reverse just reversed the direction of low range giving them a theoretical reverse speed of 9 mph. The M1 does the same for 1st and 2nd gears giving it a 20 mph reverse speed.


I was always struck more by how fast an M1 unit could displace more than the speed of an advance/attack.

Not being around tanks much in ROTC, other than seeing them roll down tank trails or in branch day, and then in the Armor School (and the usual newbie clusters while maneuvering), it wasn't until arriving at my first unit and doing company lanes that I realized the violent speed in withdrawal as platoons pulled out of line, and a whole company repositioned.

Any idea on reverse speeds of various BTR series vehicles?

Any idea on M113 reverse speeds, or at least gear ratios, either for Allison TX-100 or upgraded transmissions on M113A3?

Some people would suggest that the Archer     ( SP 17pdr, Valentine, Mk I, Archer    not the FH77)    always traveled in reverse anyway

TM 9-2350-277-10 says the max reverse speed for the M113A3 family is 6 mph. TM 9-2350-261-10 for the -A2 family doesn't list a reverse speed, but TM 9-2350-247-10 for the M548A1/A3 says 9.2 mph for the M113A2-based M548A1. Contrarily, though, it lists the M113A3-based M548A3 as being limited to 4.5 mph, so it may not directly correlate.

TM 9-2350-215-10 (1965) gives 5mph max reverse speed for the M60/M60A1.

Many thanks, Chris!

Somehow related, I calculated M114 reverse speed as 7.9 mph, corroborated with low gear speed being listed as 8mph.

TM 9-2350-257-10-1 (Operator's Manual-Operator Controls and PMCS-Tank, Combat, Full Tracked-105-MM Gun, M60A1 (Rise) 1980) reads reverse speed as 7 mph.

In case somebody run into this:

 

BTR-70 is listed as 10,3 km/h; BTR-80 is 11,7 km/h.

 

According to my calculation, BTR-60 should have the same reverse speed as BTR-70, and they share gear ratios.

No kidding. 4 km/h reverse speed on the T-72 is nothing but a liability.
