First let's define the problem.
- The mortar pit can hide behind buildings protected by vickers,
- the mortar pit is immobile and a target practice for leig
- the mortar pit is too durable

A Flying Pit Wolfpack Formation
- It will have to constantly fly and relocate, thus it will be vulnerable to AA. Vulnerability to AA will be a new weakness
- It will gain the much needed mobility and thus escape the leig spamfest
