Mortar Smoke

When you need to take off the last few VPs, lay smoke on the point and cap. You can cap under some serious fire when in smoke cover, and take very little damage or supression. You can cap in front of MG bunkers no problem. I won a game when in a similar situation, by capping with a mortar under the cover of it's own smoke under fire from a KT, an MG, an MG bunker, and more :D. Only things you really need to worry about are flames, grenades and artillery.

You had the early and middle game, instead of spamming rangers some ATs with rifle covering it and mgs would be better counter to all anti-infantry units that he had( pumas, Ostwinds) and KT.you could make an howie too, it coulded help you much more than the wasted manpower in rangers ( to counter mgs in middle, bunkers in VP, and any units that could be camped in VPs).
