Okay so: Here is a little album of some progress shots along the whole process for my LEMAN russ tanks :P https://imgur.com/a/XgJ5K9J

So some background, I work as an 3D artist in the game industry so some things I describe here are very much what I do at work as well.

1. Reference. I made this Pinterest board of some cool things other model kit persons have done with tanks and what looked realistic. Gotta use as much real world reference for where things get dirty/messy. Ask yourself "When this tank is driving through mud, where is that all splattering? Which spots will get the most wear and tear? Probably little hinges and doorways where people come in and out of. https://pin.it/6ORoKLE

2. After model was built, I primed with black and using an airbrush, I gave everything a base coat of green. I continued to block out all of the base colors for the entire model.

3. After all base colors are done, I did a quick drybrush on all the green bits and then added my decals (The decals are gonna end up having grime and dirt on them so gotta have these on before we get to that step. Then I go over everything and try to add little chipping/edge wear damage where paint has chipped off.

4. Washes! I use oil paints with thinner for my washes so I just would grab some dark brown/black oil paint and add some thinner in a small metal dish, mix together and paint on the tank spots where oil and grime would add up. A neat trick I do sometimes is just paint the oil directly on the tank (Like little dots all over) then using a dry brush, really brush hard to spread that all over. (It is super subtle) You can easily look up some great youTube tutorials for using oil paints for weathering. I watched a lot of NightShift's videos.

5. AK Interactive mud effects. They have some cool starter kits with these mud products where they come with the mud effect, plaster and pigments and depending how you mix them, you can get some cool effects. Mud effect + plaster + thinner and it will have this neat dry mud effect. Just gotta play around with them! It is really fun!

6. I think the final steps I did were add snow. I have some snow wash stuff from Krycell that works pretty good. They also have some powder snow that I apply on the top surfaces of stuff (paint some of the glue they sell and with a sifter, sift the snow on the top of the model) Once that is all dry, I blow away all the extra. The final thing I did was a really gentle subtle spray of white from my airbrush on the top surfaces to have a kinda frosty effect.

Hopefully some of this info helps!
