- The Command & Conquer Wikia article on Militants references the C&C3:TW Nod Faction Feature on IGN for the statement that Nod Militants still use the GAU-3 Minigun by the time of the game. If this is true, their damage per-shot should be physically identical to that of Minigunners in TD. Nod Militants inflict 9 damage in TW, while Minigunners inflict 15 damage in TD. If those damage values both represent the same physical damage, then the ratio is 15:9. So 60% of a given TD damage value in TW represents the same physical damage as that TD damage value. Consequently, a multiplier of *(1/0.6) applied to a TW damage value results in a number that represents the same physical attribute in TD terms. (Disclaimer: That the TW value and TD value represent the same physical damage is tentative, as the comparison may be polluted by divergent accuracy values - the lower damage of Militants may represents that they aim less precisely than the professional military Minigunners in TD. This is a case that can reasonably be made, but I dismissed it for the purpose of this consideration.)
- Less evidential, but an indication that this calculation is on the right track: GDI Riflemen in TW have 75 HP. Light Infantry in TS have 125 HP. The proposition that there have been no substantial advances in infantry armor between TS and TW may be plausible, so that we could consider the 75 HP of TW, and 125 HP of TS, to represent the same physical resilience. Incidentally, applying the multiplier of *(1/0.6) to 75 gives a result of 125.
- On the other hand, the same multiplier applied to the Militant's 40 HP only results in a lowly ~67 HP. But unlike the Rifleman, who is visibly and lore-wise far more similar to the Light Infantry, the Militant is clearly inferior to the infantry fielded by Nod in TS in both armor and training, so a lower value should be expected and does not at all make the multiplier implausible.
So, from this guesstimation, applying *(1/0.6) multiplier to the HP and damage values of C&C3:TW should result in the values that accurately represent their characteristics relative to the values used in TS, and vice versa.
(As I've detailed elsewhere, presumably these stats can further be transferred 1:1 to RA2/YR and Gen/ZH.)
