So, what units would you recommend me getting to start off?
Well, Company Command and two platoons are necessary. Each platoon has to be made up of a Platoon Command Squad and 20 Guardsmen. So, that's the necessary part. A codex is also great help.
After that, it's all about the style you'd rather play:
If you want a "defensive" army that has to move very little, the "gunline" is a classic formation. This one needs a lot of bodies and a lot of guns, so Guardsmen and Heavy Weapon Squads should be a priority. After that, artillery, transports and elite squads. Finally, a few tanks and smaller vehicles for tactical maneuvers.
If you want a "mobile" army, then transports, fast-moving vehicles and tanks. Artillery is basically useless, heavy weapon squads as well. These have to secure objectives quickly and defend them. They're good at attacking and taking objectives, but their biggest defense is just running from a fight, when it isn't necessary.
For a "slow attack" army, you'd want a little bit of everything, but tanks and infantry are priority. They just have to move slowly, using tanks for support to take down big enemies and the infantry should be able take care of themselves.
There are far more many types, but these are, or I've been told so, are the most "basic" of the Imperial Guard. Tactics are crucial for smaller forces, seeing as the Guard's strength lies completely in it's guns and vehicles.
Personally, I found it helpful to get a lot of guardsmen and heavy weapon squads first, since what the Guard lacks in stopping power, it makes up for in numbers. These should be a priority for most new players, since the sheer amount of guns is the best thing about the guard. Then, tanks and artillery.
For a Guard player, it's best to have a little bit of everything, even though it's possible to beat the enemy with any army combination possible. Of course, that's just my opinion.
