one of the great crowning moments in online play involved sneaky SRM carriers.
way back in 1994, there was BattleTech 3056 MUSE, which held a 5-day battle of Tukkayid scenario, As the hours wound down on the very last day of the battle, Comstar was almost entirely out of Mechs. The clan side was equally low, With Comstar still holding 5 of the 9 bases, with 10 minutes left, a lone Masakari-C started pounding one of the bases at range 2. If he destroyed the base before time ran out, the Clans won. In the base were 2 SRM carriers and an Ontos.
on a 3 count,all 3 popped out. (basically a surprise reveal of 2 SRM carriers in the same hex, range 2.) forst salvo sanded all the armor off the mech and did a gyro. ontos, popping out a moment later, plus the second srm salvo, completely destroyed the mech. It was actually the very last assault mech the clan side had, and nothing they had left could reach the base in time to shoot it up, making those 3 tanks the great heroes of that battle.
NEVER underestimate what a suprised, hidden unit can do.
