In the book 2 or 3 colours are used to make one for each colour in the camo but is there an alternative to all this mixing or is it needed to get a life like camo uniform?
Basically, yes. As an alternative you could get the entire Vallejo Model Colour range and for a subject like this just use whatever they offer that's closest to what you need, but that's pretty limiting. You can certainly do this initially when mixing colours is harder for you, but I'm not really recommending this, case it's not clear; you will need to learn to mix colours to some degree anyway and now is as good a time as any to start!
If it helps, the more you paint the less onerous mixing will seem. Anyone painting in oil paints or other artists' colours will have to mix uniform shades 'from scratch' using bright colours; as hard as this seems it's really not a huge burden once you get used to it.

...suppose I better start learning about colour theory, I mainly use vallejo acrylics and they offer a huge range of colours but am I best off learning colour theory and mixing my own colours whilst comparing it to a reference?
Colour theory unfortunately only takes us so far and a great deal of the useful stuff that a wheel can actually offer us in terms of mixing advice you already know I'm sure (the basics, like blue + yellow = green, yellow + red = orange). The stuff that's more complex than this - like where is buff, or khaki, or brown generally? what do I get when I mix
this red with
this blue? - colour wheels usually can't help with.
But the good news is you're in the right place since people will have tackled many of the same colours you're looking for and can give you suggestions on what to use.
Other than that I would encourage you to play around on the palette with your paints and see how mixtures of X and Y work, firsthand. Sometimes it's quite surprising the colour you get when paints mix and the best way to learn this is to see the results with your own eyes.

also I brought tamiya's German infantryman in the reversible uniform but I don't think it came without camo on one side and I don't really want to try painting a white uniform just yet.
White is in many ways less challenging than a multi-coloured camo
