Well, figured I would post a breakthrough technique that I used yesterday on Minsk to break through the well-defended first flag. I have screenies!
I started SL, and waited to see which side more of my team spawned on.
A little hard to make out, but there are more people on the left side of the bunkers. So I spawn in sniper with cloak/ghost. My squad holds spawn. I was planning on passing that squad, laying my ghost on the corner of the bunker, and cloaking around them, but...
That hillside provided a perfect vantage point, and rockets were flying everywhere at our squads. I ordered everyone to spawn in, hopefully providing enough fodder for me to pass unnoticed while stealthed.
My squad has only two defenders directly between us and freedom. We take them out, but a few enemies notice our attempt, and quickly cross over to help defend that flank.
They take us out.
Or so they thought =P Muahaha the diving revive of LOVE!!
But seriously, I did die there.
I told my squad to hold spawn, and seeing that some of the enemy forces that were on the right flank had moved left, I decided to spawn in on the right side.
The right side is slightly better for stealthing by, since you can climb the hill to the right (going slightly out of bounds), which gives you more distance between you and the enemy line to your left, near where the screenie is taken (I think I am traveling out of bounds, cloaked).
I ran to the right, laid a ghost as close to enemy lines as I could without being shot, and ran as far as I thought was safe without any possibility of being seen, then ordered my squad to spawn in and attack their defenses there.
They were just distracted enough to not notice me slipping by. Once my squad had been eliminated, they respawned with me next to their Hill flag.
I ordered them to attack that flag, knowing that enemies would soon be spawning in there. I continued on past that flag towards the back flag.
Before:
After:
lol.
I sent them back to that flag once more to be sure all defenders were occupied while I slipped away.
My reasoning behind these attacks on hillside were not just to distract the enemy to ensure my survival, but also to take that flag, and hopefully the back one as well, with me providing a spawn point just in case. Unfortunately their defenses at Hill were bulked up, and the flag was not capped by these attacks. My squad was ordered to spawn in near me and head towards the back flag.
Everyone on EU that was ordered to defend hill is now spawned in there with nothing to kill, since the rest of my team is still at the front bunkers. That leaves them with no quick way back to their rear flag (no one dies from an attack), leaving it all alone for my taking =)
OM NOM FLAG
Hide a beacon somewhere nearby, just in case the hill defense catches up with you before your team realizes that they should spawn in the back flag (took a few minutes for PAC to start spawning in there). Defend that back flag with your life, or until your commander orders you away on another attack =)
This is just one of the possibilities of how to break through at minsk against other
TG players (this was during primetime). This tactic can also work on other maps, such as fall of berlin (I'll post a tactic on that later, when the map actually comes up in rotation...)
