Anyone know what this insignia represents? FSFB with Red Triangle “TTU”

Alright everyone, this is a new one that I just added to the collection. A fellow collector believes the markings are from  a USMC Amtrak unit. Just curious if anyone has seen something like this or knows what exactly the insignia means… thanks in advance!

My guess was Texas Tech University. Perhaps an ROTC color guard helmet.

Here’s an update! Apparently, the TTU means, “Tank Training Unit”. I have a picture of the sign I found. Here is a USMC knapsack with an upside down triangle stenciled on. The knapsack was definitely used by a Marine Tanker!

The picture you posted is of an Army unit I believe, based on the fact that it was taken in Germany. Sorry, but I still think it is a Texas Tech University ROTC color guard helmet.

The wide stripe across the top in indicative of training units. That is not necessarily saying it is a training helmet nor am I saying it is ROTC. Just pointing out the use of a wide painted stripe.

It was not uncommon for Marines to go to the Army's Armor School simply because the demands for armor in the Marines were not enough to justify their own Armor school.
