Tanker Boots and Nylon Body armor for everyone, with optional steel inserts
M1 Helmet liner is OK, very good even. Shape could have been better, but was huge improvement over the Kelly.
On the .276 Garand, have a muzzle device permanently attached for launching grenades, with a fold out ladder sight, when deployed, will shut off the gas automatically.

C-Rations, include a fold up stove in each 5 in 1 box, and each meal comes with a few Hexamine or Trixane tablets for that stove, rather than one Coleman Stove per squad that ran off gasoline.
