Oh no... a rulebook.... like that hasn't been attempted before. Welcome to the GON forums Radioman.... they've been around for all the years we've been playing Warfare here
I was Mashman (for once). I took Guglovo and Stary Sobor (solo), and then went south, located base, built MASH, and used satchels to blow up the LF and B. We already had LF1 and G1, and I never touched the MHQ. 900SP was not much of a loss as OPFOR were winning anyway.
You don't need satchels in the early stage of the game. It's just rubbish you need to keep them so "we can blow up resistance tanks"
Move satchels to G2 or G3.
An hour and a half later, after a very well balanced game (940 OPFOR vs 917 BLUFOR) the OPFOR team ran out of tissues, so they sold up their base and ended the game (after the Commander drove the MHQ right into our base).
If the concrete walls are $200+ each, they won't be spammed.
You can get rid of them though, just reduce the collision radius so they can be packed a little closer together.
