Buratai rewards gallant soldier with promotion

I think there may be a slight mistake in your statement. Buratai is a surname, and it's not a person who can reward a soldier with a promotion. Additionally, Buratai is not a common surname in Nigeria, where the Nigerian Army is based.

However, I'm assuming you meant to say that General Tukur Yusufu Buratai, the former Chief of Army Staff of the Nigerian Army, rewarded a gallant soldier with a promotion. If that's the case, I'd be happy to help you with the correct information.

Could you please provide more context or clarify which soldier was promoted and what was the occasion for the promotion? I'll do my best to provide you with accurate information.
