Support my friends?

I'm pretty sure that valkyria chronicles is supposed to be a teamwork based game, so I should probably do whatever I can to keep us all supplied and healthy.

Looking at the town watchmen and Alicia, I toss the grenades I have available and begin to fire in the general direction of the imperial troops. At this point I probably should have realized that I am a close to endgame engineer, with one of the best gallian rifles, but I continued to mechanically sight and shoot at any imperial troops that approach. I hear a shout of "DUCK" right before one of the town watchmen shoots at a sniper right about to stab me in the back! I pull out a service pistol and pop the imp in the chest before kicking him off my perch. machinegun fire peppers our position as one of the town watchmen take a round to the chest and a lucky antitank round blows away another.

There is one tank remaining.

The town watch has used up all your grenades
