Alright, Let's get started because we have a lot to explain here...
First of all i think it's important to explain that, for a context (and kind as a strength show off) all the flags removes the (so Proud) Lone star from the flag, once it shows as a mark of independence and self sufficiency, and definetly if i was to break texas spirit, that would be my first move...
The First flag goes simple it replaces the Lone Star for the Coach of arms of the USA, showing the Unity in Strength and subordination of the re-taken state.
This flag perfectly fits a medium agressive scenario, like the resistence for a government change or etc.

The Second one is pretty much like the first but it also has the "Semper Fidelis" putted on the flag as both a mock of every Texan Military veteran, but also as a reminder of the control and the real leader of the texan state.
U could also say that after the Marines occupation of texas, it became a military ruled state by the Corps, applying that phrase as a state policy used to bend the rebelious back to their position.

This One has 6 Stars around the coach of arms, they represent the historical dominance of texas, French, Spanish, Mexican, Independent, American and the sixth one the current state, that could be not occupied but anexed, not just as a federation, but as a subjugated territory.

This one is just for fun, if texas was taken back by the Mexicans, It looked nice...
