As the title implies I'd like to hear the ins and outs of using the Land Mattress.
I got several years of COH1 an COH2 experience, with mostly Ostheer, OKW and UKF forces.
The thing is I haven't used the commander that gives you a Land Mattress. Therefor I would like to know the ins and outs since I am getting more and more interested in artillery equipement.

Firestorm Doctrine

Although I am very aware about this doctrine not being an OP doctrine, I for one am very fond of the flamethrower ability to equip one or more Sturmpioniere with.
I wish to use this doctrine simply for nostalgic reasons and my preference to play with fire, lets say I like to live dangerously.

I have read many articles about OKW and sadly only a few were written about the OKW Firestorm Doctrine, those that were written about it are mostly negative and not very helping strategic wise.

My question to all the experienced players is if you could tell me how I could use this Doctrine usefully. I am an aggressive type of player that likes to overwhelm opponents early on.
My preference is to do this with Sturmpioniere + Flamethrowers (for buildings/green cover mostly)

There are lots of tips I am sure that can be provided, also I could use some nice intell about manouvres to cut off people on the most popular tournament 1vs1 maps (can someone make a top 3 1vs1 map with names).

I would like to learn these tactics with the new intell on these maps so I can try some ranked matches later.

Auf wiedersehen,
