historical strategy where i can cheat by introducing more modern technology

For the last year i've been playing a heavily modded Victoria 3 where the scenario is that i introduce semi automatic rifles and belt fed machine guns to my armies before 1850. Which makes my rather tiny nation able punch way above its weight and rewrite history .

However. Victoria 3 is more focused on trade and colonization than it is warfare.

Are there any other strategy games that are more focused on warfare but makes a similar scenario possible?
