Putin has an amazing method of recruitment

He contracted mercenaries to arrange, form, and train a privately paid army as an adjunct to his Russian forces. Recruitment of volunteers was en-mass from Russian prisons and volunteers. It allowed promises to be made that no regular army grunt could think of. Now after that was done he’s sacked the head contractor and “blackbirded” the private forces into his regular army cutting out the middleman and saving himself millions in the process and saving any further embarrassment of comparing the competency of the two forces at the same time. After all the prison rabble couldn’t be seen to be better-trained fighters than his own Russian Force.
