    • M113 Super Gavin T150 Track Shoe Extensions “duck bills” In WW2, M4 Sherman tanks as extra armor was added lost mobility due to narrow tracks, resulting in battle and Soldier losses. “Duck Bill” extensions helped regain mobility. Today’s M8 Buford/Thunderbolt/Tracer AGS and M113 Super Gavins with extra armor need their tracks widened to compensate for add-on armor and improve mobility in mud, snow/ice and water. A reversible rubber pad with a metal core extending out with a mud and water swimming tread and an snow/ice tread on the opposite side could achieve this.

    • U.S. Army Light Infantry Needs M113 Gavin Light Tracked ArmoredFighting Vehicles for go-anywhere-in-the-world mobilityFalklands War decision: what would U.S. light infantry do? Brigadier JulianThompson in his book, No Picnic on page 11 writes:"I was decided at an early stage in planning to take the minimum number ofwheeled vehicles. The going anywhere in the Falklands away from thesettlements was so bad that even a lightly loaded Landrover would be lucky tocover four miles an hour. Vehicles loaded with ammunition and stores would belucky to move at all. The Brigade did have seventy-six of its BV202 oversnowvehicles in England, the remainder being stockpiled in Norway. Althoughdesigned to operate over snow there was a good chance that these vehicleswith a ground pressure of only 1 1/2 lbs per square inch, about that of a man onskis, would be able to motor across the peat bog. Events were to prove theycould."How many tracked vehicles do U.S. Army light infantry unitshave now? ZERO.They have lots of 3-ton Humvee and 10-ton LMTV and FMTV trucks, why not10-ton M113 Gavin light tracks? We have THOUSANDS in storage.

    • “It had rained practically every day and the ground was saturated, making movement bytanks and other armored vehicle extremely difficult. The inability of our medium tanks tonegotiate soft ground had been recognized some time before, and field servicemodification kits had been sent forward to be installed on the tanks. The kits consisted ofthree-inch-wide steel grousers, which were attached to the track connectors on each trackblock on both sides. This gave an overall width of twenty inches compared to thirty andthirty-six inches on German tank tracks. I contacted Dick Johnson with the 33rdMaintenance and arranged to have their supply truck pick up the boxes of grousers at theordnance battalion headquarters company. The grousers finally got down to the tankcrews, who installed them on their own tanks. The tank crews were enthusiastic about thegrousers, which did help somewhat, but the ground was so completely saturated that thegrousers only partially solved the problem. Our tanks still got stuck easily. The problemwas that the grousers were designed so they did not come in full contact with the grounduntil the tank had already penetrated the outer crust. Thus, the breakthrough of the crusthad already occurred and the tank could still sink down further due to the shearing action.I’d venture to say that the fields around Kornelimunster, Mausbach, and Breinigare still filled with left-over grousers and spare locknuts.”--Former U.S. Army 1st LT Belton Cooper in Death traps: the Survival of an American Armored Division in WW2,pages 153-154 MkVI Tiger M4 Sherman heavy tank medium tank 30-36 inches 17 inches
