I certainly hope Texas law enforcement can secure our border without the help of militia. I am a fan of militia but history teaches us militia is undisciplined, unpredictable and prone to making well meaning mistakes. That said if the job is more then DPS and that Texas State Guard can handle then by all means call up the militia and let me know if they need a 66yo long time inactive Marine.
A 66yo inactive Marine is worth 10 of the citizen types we have today.
The Texas State Guard is militia. A select militia to be sure, but militia none the less. National Guard was militia too, before being turned into a branch of the Federal Military reserve. Of course in another sense, even Guard and Reserve forces are militia, part time soldiers, sailors, airmen and Marines, but they are federal militia.
I've been active duty, reserve and national guard. I'm now too old for even the Texas reserve militia, which is everyone, men and women, save a few public officials, 18 through 60. We are both too old even for the federal militia, which requires one to be under 64 and it's 45 for non prior service men.
