Would you translate this for me please?

Would somebody be kind enough to translate this patch for me? And tell me what it was for? Thanks

"GUARDS (adjective emphasis - as opposed to the noun: "GUARDS" on the depicted badge shown above the tank) SHEPELOVKA'S (SHEPELOVKA is a small town) TANK REGIMENT 12"

SO, it is: "GUARDS SHEPELOVKA'S TANK REGIMENT 12"

"(FOR) MOTHERLAND, DUTY, AND GLORY"

The rest I leave up to you to research, as I do not know...
