2MAU Iron-man is fully capable of detecting beings that use cloaking devices.
Composite 2MAU Iron-man is a casual lighting timer with striking power enough to hurt quantum power Thanos (A planet buster), the strength enough to wrestle with quantum power Thanos, the durability enough to to tank multiple blows from Quantum power Thanos and dozens of strikes from a blood-lusted Beyonder. His ranged attacks are powerful enough to rock Odin, he posses the ability to absorb and leach energy directly from his opponents. On top of all that Iron-man posses the ability to heal his armor completely from any and all damage that it has taken. I'm not sure how Warmachine can win this.
The characters that War Machine hangs with and harms are a lot more durable and consistent than the high tiers in the AA universe where they consistently have trouble with even the lower tiered Avengers like Hawkeye, Captain America, and Black Widow. The only way to properly gauge the power levels in that universe is to look at high and and low end feats and meet somewhere in the middle.
