Jack Marshman thinks his resilience comes from his time in the British Army
Marshman (21-5) will fight in the UFC for just the second time tonight in Halifax where Derrick Lewis and Travis Browne top the card.
The Welsh middleweight beat Sweden's Magnus Cedenbled on his UFC debut in November and hopes that victory over Thiago Santos will earn him a bout against a fighter in the top 15.
And the 27-year-old will look to draw on his 10 years of military experience with the 3rd Battalion, Parachute Regiment if he finds himself in trouble early.

"The Octagon is a whole different scenario [from the army] obviously," Marshman told Express Sport.
"There's one other guy in there with you and only one of you is winning.
"When you're in a battle, you've got your friends supporting you and you're fighting a common enemy.

"But I've experienced a lot.
"You've only got to watch my fights to know I'm resilient – I usually take a beating in the first round and come back stronger in the second.
"I'm a tough guy and the army definitely gave me some of that, whether it was from Afghan or just in general.
Jack Marshman was the first Welshman to sign a UFC contract
"It's a tough career and I did it in the best regiment in the army.
"They give you a lot of strength mentally and some good discipline as well."
Marshman was the first Welshman to sign with the UFC in October and wants to fly the flag for his country with an event on home soil.
To do so would be the completion of a journey that started when he was a teenager who learned mixed martial arts as a way of staying out of trouble.
"My dad was friendly with [MMA coach] Richard Shore," Marshman added.
"He took me to a gym when I was 14 or 15 and I never looked back. I stayed in the gym and it's what I spent all my time doing.
"I absolutely loved it. I just enjoy competition and trying to be the best.
"At one point I was in a lot of trouble with the police and that changed from then.
"After that, I spent 10 years in the parachute regiment.
"At 15 to think that I would be in the army at 17 and the UFC at 27 – you really wouldn't have believed it."
