Mil-Comm TW25B synthetic weapons grease... Son-in-law told me about it, it's what was issued to him in his deployments to Iraq.

I discovered that a little goes a long way... I bought a 4 oz. tube, it's going to end up outlasting me.

Probably close to Tetra grease... I suspect like gasoline brands, the formulation of synthetic grease base is all the same, to only thing that distinguishes one from another is the proprietary additives/formulation, and in the end, one works as well as the other.
