Easy way to get Great Guard Veteran?

[Yesugey]

Thanks all you guys for the answers.

Zarobien, AMP thanks for golden information. I couldnt agree more that cavalry always finds some bowmen to kill on 4vs4 fights. And I never played custom battles but if its against computer, they sound like "free vet unit" to me already.

I will use these on weekend, and post the good news hopefully

AMP and Zarobien, I have my first Vet Greeat Guard and few No-Dachi, thanks to your tips. I just built an army with all vets except the Guards. Now its time to have more archers :)
