Charlie TeamSeal 3 Platoon Bradley Cooper Movie Cap Hat M/L

Is it okay to buy this hat as a civilian? i think of chris kyle as a hero and i don't want to disrespect him by wearing a hat he earned the right to.

Is this a low profile hat or will it sit up high?

How do I make the hat fit better?

I'm 7 1/2, ¿will this fit me?
